Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of business and significant accounting policies and practices	Description of business and significant accounting policies and practices. Texas Instruments (TI) designs and makes semiconductors that we sell to electronics designers and manufacturers; more than 80,000 customers all over the world buy our products. Basis of Presentation — The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the U.S. (U.S. GAAP) and on the same basis as the audited financial statements included in our annual report on Form 10-K for the year ended December 31, 2010. The consolidated statements of income, statements of comprehensive income and statements of cash flows for the periods ended September 30, 2011 and 2010, and the balance sheet as of September 30, 2011, are not audited but reflect all adjustments that are of a normal recurring nature and are necessary for a fair statement of the results of the periods shown. The consolidated balance sheet as of December 31, 2010, presented herein is derived from the audited consolidated balance sheet presented in our annual report on Form 10-K at that date. Certain amounts in the prior periods’ financial statements have been reclassified to conform to the current period presentation. Certain information and note disclosures normally included in annual consolidated financial statements have been omitted pursuant to the rules and regulations of the U.S. Securities and Exchange Commission. Because the consolidated interim financial statements do not include all of the information and notes required by U.S. GAAP for a complete set of financial statements, they should be read in conjunction with the audited consolidated financial statements and notes included in our annual report on Form 10-K for the year ended December 31, 2010. The results for the three- and nine-month periods are not necessarily indicative of a full year’s results. The consolidated financial statements include the accounts of all subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. All dollar amounts in the financial statements and tables in the notes, except share and per-share amounts, are stated in millions of U.S. dollars unless otherwise indicated. On September 23, 2011, we completed the acquisition of National Semiconductor Corporation (National). The consolidated financial statements include the balances and results of operations of National from the date of acquisition. See Note 2 for more detailed information. Use of Derivatives and Hedging — In connection with the issuance of long-term debt in May 2011, as more fully described in Note 5, we entered into an interest rate swap designated as a hedge of the variability of cash flows related to interest payments on the variable-rate portion of the debt. Gains and losses from changes in the fair value of the interest rate swap are credited or charged to accumulated other comprehensive income (AOCI). We also use derivative financial instruments to manage exposure to foreign exchange risk. These instruments are primarily forward foreign currency exchange contracts that are used as economic hedges to reduce the earnings impact exchange rate fluctuations may have on our non-U.S. dollar net balance sheet exposures or for specified non-U.S. dollar forecasted transactions. Gains and losses from changes in the fair value of these forward foreign currency exchange contracts are credited or charged to other income (expense) net (OI&E). We do not apply hedge accounting to our foreign currency derivative instruments. We do not use derivatives for speculative or trading purposes. Fair Values of Financial Instruments — The fair values of our derivative financial instruments were not significant at September 30, 2011. Our investments in cash equivalents, short-term investments and certain long-term investments are carried at fair value and are discussed in Note 8. The carrying values for other current financial assets and liabilities, such as accounts receivable and accounts payable, approximate fair value due to the short maturity of such instruments. The fair value of our long-term debt approximates the carrying value. Accounting Standards Adopted — In October 2009, the Financial Accounting Standards Board (FASB) concurrently issued the following Accounting Standards Updates (ASUs): Ÿ ASU No. 2009 - 14 - Software (Topic 985): Certain Revenue Arrangements That Include Software Elements. This standard removes tangible products from the scope of software revenue recognition guidance and also provides guidance on determining whether software deliverables in an arrangement that includes a tangible product, such as embedded software, are within the scope of the software revenue guidance. Ÿ ASU No. 2009 - 13 - Revenue Recognition (Topic 605): Multiple-Deliverable Revenue Arrangements. This standard modifies the revenue recognition guidance for arrangements that involve the delivery of multiple elements, such as product, software, services and support, to a customer at different times as part of a single revenue generating transaction. This standard provides principles and application guidance to determine whether multiple deliverables exist, how the individual deliverables should be separated and how to allocate the revenue in the arrangement among those separate deliverables. We adopted these standards in the first quarter of 2011 by applying them on a prospective basis to revenue arrangements entered into or materially modified beginning January 1, 2011. The adoption of these standards did not have a significant impact on our financial position or results of operations. New Accounting Standard Not Yet Adopted — In May 2011, the FASB issued ASU No. 2011-04, Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRS. This standard results in a common requirement between the FASB and the International Accounting Standards Board (IASB) for measuring fair value and for disclosing information about fair value measurements. While this new standard will not affect how we measure or account for assets and liabilities at fair value, the disclosure requirements will be required for interim and annual periods beginning January 1, 2012. There will be no impact to our financial condition or results of operation from the adoption of this new standard.

National Semiconductor acquisition

9 Months Ended

Sep. 30, 2011

Business Combinations [Abstract]

National Semiconductor acquisition

National Semiconductor acquisition. On September 23, 2011, we completed the acquisition of 100% of National’s issued and outstanding common stock. National designs, develops, manufactures and markets a wide range of semiconductor products, focusing on providing high-performance energy efficient analog and mixed-signal solutions. The purpose of the acquisition was to grow revenue by combining National’s products with TI’s larger sales force and customer base.

We accounted for this transaction under Accounting Standards Codification (ASC) 805 - Business Combinations, and National’s operating results are included in the Analog segment. The amount of National’s revenue included in our consolidated statement of income for the period from the closing date to September 30, 2011, was $18 million.

As of September 30, 2011, the allocation of the consideration transferred to the assets acquired and liabilities assumed from National is not yet complete. The preliminary estimates of fair value by major class of the assets acquired and liabilities assumed at the acquisition date are shown below. Because the acquisition closing was near our September 30 quarter-end date, these amounts are based on preliminary valuations. They include work performed by third-party valuation specialists retained to assist management in its valuation efforts, as well as our own estimates and assumptions. These preliminary fair value estimates are subject to change as valuations are finalized.



Cash and cash equivalents	$	1,145
Current assets	455
Inventory	225
Property, plant and equipment	904
Other assets	227
Acquired intangible assets (see detail below)	2,974
Goodwill	3,527
Assumed current liabilities	(195		)
Assumed long-term debt	(1,105		)
Deferred taxes and other assumed non-current liabilities	(1,600		)
Total consideration transferred	$	6,557

The acquisition date fair value of the consideration transferred is as follows:



Cash payments	$	6,535
Fair value of vested share-based awards assumed by TI	22
Total consideration transferred to National shareholders	$	6,557

The total cash flow impact of $5.390 billion results from the $6.535 billion cash payment offset by $1.145 billion cash balance of National at closing.

Identifiable intangible assets acquired and their estimated useful lives are as follows:



	Asset amount		Weighted average useful life (in years)
Developed technology	$	2,025	10
Customer relationships	810		8
Other	34		5
Identified intangible assets subject to amortization	2,869
In-process research and development	105		*
Total identified intangible assets	$	2,974

* In-process research and development is not amortized until the associated project has been completed. Alternatively, if the associated project is not viable, it will be expensed.

We utilize the straight-line method of amortization for acquired intangible assets. Amortization of acquired intangible assets prior to the National acquisition was $19 million and $38 million for the nine months ended September 30, 2011 and 2010, respectively. Amortization of acquired intangible assets from the National acquisition is a component of acquisition cost, which is detailed later in this note. We recognized $6 million for the period from the acquisition date to September 30, 2011.

The remaining consideration, after adjusting for identified intangible assets and the net assets and liabilities recorded at fair value, was $3.527 billion and was applied to goodwill. This goodwill is attributed to National’s product portfolio and workforce expertise. None of the goodwill related to the National acquisition is deductible for tax purposes.

The following unaudited summaries of pro forma combined results of operation for the three months and nine months ended September 30, 2011 and 2010, give effect to the acquisition as if it had been completed on January 1, 2010. These pro forma summaries combine the historical results of TI for the three months and nine months ended September 30, 2011 and 2010, with the historical results of National (which had a year-end in May) for the three months and nine months ended August 28, 2011, and August 29, 2010, respectively. These pro forma summaries do not reflect any operating efficiencies, cost savings or revenue enhancements that may be achieved by the combined companies. In addition, certain non-recurring expenses, such as restructuring costs and retention bonuses, that are expected to be incurred within the first twelve months after the acquisition are not reflected in the pro forma summaries. These pro forma summaries are presented for informational purposes only and are not necessarily indicative of what the actual results of operations would have been had the acquisition taken place as of that date, nor are they indicative of future consolidated results of operations.



	For Three Months Ended Sept. 30,				For Nine Months Ended Sept. 30,
	2011		2010		2011		2010
Revenue	$	3,818	$	4,152	$	11,385	$	11,613
Net income	589		887		1,930		2,269
Earnings per common share - diluted	$	0.50	$	0.73	$	1.61	$	1.83

Acquisition cost

Included in the acquisition cost line of the Consolidated Statements of Income are the following:



	For Three Months Ended Sept. 30,				For Nine Months Ended Sept. 30,
	2011		2010		2011		2010
Transaction costs	$	30	$	—	$	45	$	—
Restructuring costs	53		—		53		—
Stock-based compensation	41		—		41		—
Accrual of retention bonuses	6		—		6		—
Amortization of intangible assets	6		—		6		—
Other costs	11		—		11		—
Total	$	147	$	—	$	162	$	—

Transaction costs include expenses incurred in connection with the National acquisition, such as investment advisory, legal, accounting and printing fees, as well as the costs associated with the bridge financing obtained in April 2011.

Restructuring costs associated with the National acquisition consist of severance and other benefit payments for former National employees who have been or will be terminated after the closing date. About 350 jobs will be eliminated by the end of 2012. Additional restructuring charges of about $30 million for this action will continue through the third quarter of 2012.

Stock-based compensation of $41 million was recognized for the accelerated vesting on employees being terminated. Additional stock-based compensation will be recognized over any remaining service periods.

The accrual of retention bonuses reflects amounts to be paid to former National employees who fulfill agreed upon service obligations. This expense will be recognized ratably over the service period. We accrued $6 million in the third quarter and the remaining expected charges of about $75 million will be recognized by the end of the first quarter of 2012.

Amortization of intangible assets is based on an estimated average useful life varying between 5 and 10 years. Annual amortization for the next 5 years is about $325 million per year. See Note 3 for additional details.

Goodwill and Intangible Assets Disclosure [Abstract]

Goodwill and other acquisition-related intangibles

Goodwill and other acquisition-related intangibles.

Changes in goodwill as of September 30, 2011, by segment are as follows:



	Analog		Embedded Processing		Wireless		Other		Total
Goodwill, December 31, 2010	$	630	$	172	$	90	$	32	$	924
Additions from acquisitions	3,527		—		—		—		3,527
Goodwill, September 30, 2011	$	4,157	$	172	$	90	$	32	$	4,451

There was no impairment of goodwill during the nine months ended September 30, 2011. Goodwill in the Analog segment increased as a result of the National acquisition. The goodwill balances shown on our balance sheets are net of total accumulated amortization of $221 million.

The following table shows the components of acquisition-related intangible assets as of September 30, 2011 and December 31, 2010:



		Sept. 30, 2011						Dec. 31, 2010
	Amortization Period	Gross Carrying Amount		Accumulated Amortization		Net		Gross Carrying Amount		Accumulated Amortization		Net
Developed technology	4 - 10 years	$	2,180	$	117	$	2,063	$	155	$	100	$	55

(a) Not yet subject to amortization.

In the nine months ended September 30, 2011, we recognized intangible assets associated with acquisitions of $2.974 billion.

Amortization of acquisition-related intangibles was $25 million for the nine months ended September 30, 2011, primarily related to developed technology. This amount included $6 million of amortization expense related to the intangible assets acquired through the National acquisition.

Losses associated with the earthquake in Japan	9 Months Ended
Losses associated with the earthquake in Japan	Sep. 30, 2011
Losses Associated with the events in Japan [Abstract]
Losses associated with the earthquake in Japan	Losses associated with the earthquake in Japan. On March 11, 2011, a magnitude 9.0 earthquake struck near two of our three semiconductor wafer manufacturing facilities in Japan. Our manufacturing site in Miho suffered substantial damage during the earthquake, our facility in Aizu experienced significantly less damage, and our site in Hiji was undamaged. We maintain earthquake insurance policies in Japan for limited coverage for property damage and business interruption losses. Assessment and recovery efforts began immediately at these facilities and officially ended in August. Our Aizu factory recovered first and has been in production since the second quarter, while our Miho factory opened a mini-line for products in mid-April and was back to full production this summer. During the first nine months of 2011, we incurred gross operating losses recorded in Other of $98 million related to property damage, the underutilization expense we incurred from having our manufacturing assets only partially loaded and costs associated with recovery teams assembled from across the world. These losses have been offset by about $20 million in insurance proceeds related to property damage claims. Almost all of these costs and proceeds are included in cost of revenue in the Consolidated Statements of Income. In the third quarter of 2011, we benefited from a net reduction in cost of revenue of $1 million. In addition to the costs associated with the earthquake, we also had an impact to revenue. In the third quarter of 2011 and for the first nine months of 2011, we recognized $22 million in insurance proceeds related to business interruption claims. These proceeds were recorded as revenue in Other. We continue to be in discussions with our insurers and their advisors, but at this time, we cannot estimate the timing and amount of future proceeds we may ultimately receive from these policies.

Debt

9 Months Ended

Sep. 30, 2011

Long-term Debt, Unclassified [Abstract]

Debt

Debt. The balances include amounts assumed related to the National acquisition measured at fair value as of the acquisition date.

Short-term — On July 14, 2011, in anticipation of the acquisition, we issued an aggregate of $1.2 billion of commercial paper, which was supported by existing revolving credit facilities. As of September 30, 2011, the balance of commercial paper outstanding was $1.2 billion.

Long-term — On May 23, 2011, we issued an aggregate principal amount of $3.50 billion of fixed- and floating-rate long-term debt to help fund the acquisition. The proceeds of the offering were $3.497 billion, net of the original issuance discount. We also incurred $12 million of issuance costs that are included in other assets and will be amortized to interest and debt expense over the term of the debt.

In connection with this issuance, we also entered into an interest rate swap transaction related to the $1.0 billion notional amount of our floating-rate debt due 2013. Under this swap agreement, we will receive variable payments based on three-month LIBOR rates and pay a fixed rate through May 15, 2013. Changes in the cash flows of the interest rate swap are expected to exactly offset the changes in cash flows attributable to fluctuations in the three-month LIBOR-based interest payments. We have designated this interest rate swap as a cash flow hedge and record changes in its fair value in AOCI. The net effect of this swap is to convert the variable interest rate to a fixed rate of 0.922 percent.

The following table summarizes the long-term debt outstanding as of September 30, 2011, including the $1.0 billion in face value of National’s long-term debt (fair value of $1.105 billion) assumed in connection with the acquisition:



Notes due 2012 at 6.15% (assumed with National acquisition)	$	375
Floating-rate notes due 2013 (swapped to a 0.922% fixed rate)	1,000
Notes due 2013 at 0.875%	500
Notes due 2014 at 1.375%	1,000
Notes due 2015 at 3.95% (assumed with National acquisition)	250

Income taxes	Income taxes. Federal income taxes for the interim periods presented have been included in the accompanying financial statements on the basis of an estimated annual effective tax rate. As of September 30, 2011, the estimated annual effective tax rate for 2011 is about 25 percent, which differs from the 35 percent statutory corporate tax rate primarily due to the effects of non-U.S. tax rates.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

Earnings Per Share [Abstract]

Earnings per share (EPS)

Earnings per share (EPS). Unvested awards of share-based payments with rights to receive dividends or dividend equivalents, such as our restricted stock units (RSUs), are considered to be participating securities and the two-class method is used for purposes of calculating EPS. Under the two-class method, a portion of net income is allocated to these participating securities and therefore is excluded from the calculation of EPS allocated to common stock, as shown in the table below.

Computation and reconciliation of earnings per common share are as follows:



	For Three Months Ended Sept. 30, 2011						For Three Months Ended Sept. 30, 2010
	Income			Shares	EPS		Income			Shares	EPS
Basic EPS:

Options to purchase 50 million and 96 million shares of common stock that were outstanding during the third quarters of 2011 and 2010, respectively, and 40 million and 96 million shares outstanding during the first nine months of 2011 and 2010, respectively, were not included in the computation of diluted EPS because their exercise price was greater than the average market price of the common shares and, therefore, the effect would be anti-dilutive.

Valuation of debt and equity investments and certain liabilities [Abstract]

Valuation of debt and equity investments and certain liabilities

Valuation of debt and equity investments and certain liabilities.

Debt and equity investments

We classify our investments as available-for-sale, trading, equity method or cost method. Most of our investments are classified as available-for-sale.

Available-for-sale and trading securities are stated at fair value, which is generally based on market prices, broker quotes or, when necessary, financial models (see fair value discussion below).

Unrealized gains and losses on available-for-sale securities are recorded as an increase or decrease, net of taxes, in AOCI. We record other-than-temporary losses (impairments) on available-for-sale securities in OI&E.

Changes in the fair value of debt securities classified as trading securities are recorded in OI&E.

We classify certain mutual funds as trading securities. These mutual funds hold a variety of debt and equity investments intended to generate returns that offset changes in certain deferred compensation liabilities. We record changes in the fair value of these mutual funds and the related deferred compensation liabilities in selling, general and administrative expense.

Our other investments are not measured at fair value but are accounted for using either the equity method or cost method. These investments consist of interests in venture capital funds and other non-marketable equity securities. Gains and losses from equity method investments are reflected in OI&E based on our ownership share of the investee’s financial results. Gains and losses on cost method investments are recorded in OI&E when realized or when an impairment of the investment’s value is warranted based on our assessment of the recoverability of each investment.

Details of our investments and related unrealized gains and losses included in AOCI are as follows:

Unrealized losses (pre-tax)	$	—	$	—	$	4	$	—	$	1	$	22

As of September 30, 2011, and December 31, 2010, the majority of unrealized losses included in AOCI were associated with auction-rate securities classified as securities that are available-for-sale. We have determined that our available-for-sale investments with unrealized losses are not other-than-temporarily impaired as we expect to recover the entire cost basis of these securities and we do not intend to sell these investments, nor do we expect to be required to sell these investments before a recovery of the cost basis. In the second quarter of 2011, we recategorized certain auction-rate securities from an available-for-sale classification to a trading classification as we intend to sell them.

For the nine months ended September 30, 2011 and 2010, the proceeds from sales, redemptions and maturities of short-term available-for-sale securities, excluding cash equivalents, were $3.25 billion and $2.18 billion, respectively. Gross realized gains and losses from these sales were not significant.

The following table presents the aggregate maturities of investments in money market funds and other debt securities classified as available-for-sale at September 30, 2011:



Due	Fair Value
One year or less	$	1,947
One to three years	168
Greater than three years	42

Fair value

We measure and report our financial assets and certain liabilities at fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date.

The three-level hierarchy discussed below indicates the extent and level of judgment used to estimate fair value measurements.

Level 1 — Uses unadjusted quoted prices that are available in active markets for identical assets or liabilities as of the reporting date.

Level 2 — Uses inputs other than Level 1 that are either directly or indirectly observable as of the reporting date through correlation with market data, including quoted prices for similar assets and liabilities in active markets and quoted prices in markets that are not active. Level 2 also includes assets and liabilities that are valued using models or other pricing methodologies that do not require significant judgment since the input assumptions used in the models, such as interest rates and volatility factors, are corroborated by readily observable data. Our Level 2 assets consist of corporate obligations, some U.S. government agency securities and auction-rate securities that have been called for redemption. We utilize a third-party data service to provide Level 2 valuations, verifying these valuations for reasonableness relative to unadjusted quotes obtained from brokers or dealers based on observable prices for similar assets in active markets.

Level 3 — Uses inputs that are unobservable, supported by little or no market activity and reflect the use of significant management judgment. These values are generally determined using pricing models that utilize management estimates of market participant assumptions.

Our auction-rate securities are primarily classified as Level 3 assets. Auction-rate securities are debt instruments with variable interest rates that historically would periodically reset through an auction process. These auctions have not functioned since 2008. There is no active secondary market for these securities, although limited observable transactions do occasionally occur. As a result, we use a discounted cash flow (DCF) model to determine the estimated fair value of these investments as of each quarter end. The assumptions used in preparing the DCF model include estimates for the amount and timing of future interest and principal payments and the rate of return required by investors to own these securities in the current environment. In making these assumptions we consider relevant factors including: the formula for each security that defines the interest rate paid to investors in the event of a failed auction; forward projections of the interest rate benchmarks specified in such formulas; the likely timing of principal repayments; the probability of full repayment considering the guarantees by the U.S. Department of Education of the underlying student loans and additional credit enhancements provided through other means; and, publicly available pricing data for student loan asset-backed securities that are not subject to auctions. Our estimate of the rate of return required by investors to own these securities also considers the reduced liquidity for auction-rate securities. To date, we have collected all interest on all of our auction-rate securities when due and expect to continue to do so in the future.

The following are our assets and liabilities that are accounted for at fair value on a recurring basis as of September 30, 2011 and December 31, 2010. These tables do not include cash on hand, assets held by our postretirement plans or assets and liabilities that are measured at historical cost or any basis other than fair value.

Contingencies	9 Months Ended
Contingencies	Sep. 30, 2011
Commitments and Contingencies Disclosure [Abstract]
Contingencies	Contingencies. We routinely sell products with an intellectual property indemnification included in the terms of sale. Historically, we have had only minimal, infrequent losses associated with these indemnities. Consequently, we cannot reasonably estimate or accrue for any future liabilities that may result. We accrue for known product-related claims if a loss is probable and can be reasonably estimated. During the periods presented, there have been no material accruals or payments regarding product warranty or product liability. Historically, we have experienced a low rate of payments on product claims. Although we cannot predict the likelihood or amount of any future claims, we do not believe they will have a material adverse effect on our financial condition, results of operations or liquidity. Consistent with general industry practice, we enter into formal contracts with certain customers that include negotiated warranty remedies. Typically, under these agreements, our warranty for semiconductor products includes: three years coverage; an obligation to repair, replace or refund; and a maximum payment obligation tied to the price paid for our products. In some cases, product claims may exceed the price of our products. From time to time, we also negotiate contingent consideration payment arrangements associated with certain acquisitions, which are recorded at fair value. We are subject to various legal and administrative proceedings. Although it is not possible to predict the outcome of these matters, we believe that the results of these proceedings will not have a material adverse effect on our financial condition, results of operations or liquidity. Discontinued operations indemnities - In connection with the 2006 sale of the former Sensors & Controls business (S&C), we have agreed to indemnify Sensata Technologies, Inc., for specified litigation matters and certain liabilities, including environmental liabilities. In a settlement of litigation with a third party, we have agreed to indemnify that party for certain events relating to S&C products, which events we consider remote. We believe our remaining exposure from both of these indemnities is approximately $200 million. As of September 30, 2011, we believe future payments related to these indemnity obligations will not have a material effect on our financial condition, results of operations or liquidity.

Segment data

Sep. 30, 2011

Segment Reporting [Abstract]

Segment data

Segment data. Our Analog segment includes the following components that are based on product lines: High-Volume Analog & Logic (HVAL), High-Performance Analog (HPA) and Power Management (Power). Following the National acquisition which closed on September 23, 2011, our Analog segment also includes National’s ongoing operations under the name of Silicon Valley Analog (SVA).

Other includes our other operating segments that neither meet the quantitative thresholds for individually reportable segments, nor are they aggregated with other operating segments. These operating segments primarily include our smaller semiconductor product lines and our handheld graphing and scientific calculators.

Acquisition cost is recorded in Other. The expense associated with the incremental fair value write-up of both inventory and property, plant and equipment will be recorded in Other as well. This inventory-related expense will be classified as cost of revenue, and we expect it to cease after the fourth quarter of 2011. This property, plant and equipment-related expense will primarily be recognized as cost of revenue, tracking the depreciable lives of the underlying assets.

With the exception of goodwill, we do not identify or allocate assets by operating segment, nor does the chief operating decision maker evaluate operating segments using discrete asset information. There was no significant intersegment revenue. The accounting policies of the segments are the same as those described in the summary of significant accounting policies.

Dividends	9 Months Ended
Dividends	Sep. 30, 2011
Dividends [Abstract]
Dividends	Dividends. On September 15, 2011, we announced a 31 percent increase in our quarterly cash dividend rate. The new quarterly dividend will increase from $0.13 to $0.17 per share, resulting in annual dividend payments of $0.68 per share. The new quarterly cash dividend will be payable November 21, 2011, to stockholders of record on October 31, 2011.

Description of business and significant accounting policies and practices (Policies)	9 Months Ended
	Sep. 30, 2011
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Use of Derivatives and Hedging	Use of Derivatives and Hedging — In connection with the issuance of long-term debt in May 2011, as more fully described in Note 5, we entered into an interest rate swap designated as a hedge of the variability of cash flows related to interest payments on the variable-rate portion of the debt. Gains and losses from changes in the fair value of the interest rate swap are credited or charged to accumulated other comprehensive income (AOCI). We also use derivative financial instruments to manage exposure to foreign exchange risk. These instruments are primarily forward foreign currency exchange contracts that are used as economic hedges to reduce the earnings impact exchange rate fluctuations may have on our non-U.S. dollar net balance sheet exposures or for specified non-U.S. dollar forecasted transactions. Gains and losses from changes in the fair value of these forward foreign currency exchange contracts are credited or charged to other income (expense) net (OI&E). We do not apply hedge accounting to our foreign currency derivative instruments. We do not use derivatives for speculative or trading purposes.
Fair values of Financial Instruments	Fair Values of Financial Instruments — The fair values of our derivative financial instruments were not significant at September 30, 2011. Our investments in cash equivalents, short-term investments and certain long-term investments are carried at fair value and are discussed in Note 8. The carrying values for other current financial assets and liabilities, such as accounts receivable and accounts payable, approximate fair value due to the short maturity of such instruments. The fair value of our long-term debt approximates the carrying value. Fair value We measure and report our financial assets and certain liabilities at fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The three-level hierarchy discussed below indicates the extent and level of judgment used to estimate fair value measurements. Level 1 — Uses unadjusted quoted prices that are available in active markets for identical assets or liabilities as of the reporting date. Level 2 — Uses inputs other than Level 1 that are either directly or indirectly observable as of the reporting date through correlation with market data, including quoted prices for similar assets and liabilities in active markets and quoted prices in markets that are not active. Level 2 also includes assets and liabilities that are valued using models or other pricing methodologies that do not require significant judgment since the input assumptions used in the models, such as interest rates and volatility factors, are corroborated by readily observable data. Our Level 2 assets consist of corporate obligations, some U.S. government agency securities and auction-rate securities that have been called for redemption. We utilize a third-party data service to provide Level 2 valuations, verifying these valuations for reasonableness relative to unadjusted quotes obtained from brokers or dealers based on observable prices for similar assets in active markets. Level 3 — Uses inputs that are unobservable, supported by little or no market activity and reflect the use of significant management judgment. These values are generally determined using pricing models that utilize management estimates of market participant assumptions. Our auction-rate securities are primarily classified as Level 3 assets. Auction-rate securities are debt instruments with variable interest rates that historically would periodically reset through an auction process. These auctions have not functioned since 2008. There is no active secondary market for these securities, although limited observable transactions do occasionally occur. As a result, we use a discounted cash flow (DCF) model to determine the estimated fair value of these investments as of each quarter end. The assumptions used in preparing the DCF model include estimates for the amount and timing of future interest and principal payments and the rate of return required by investors to own these securities in the current environment. In making these assumptions we consider relevant factors including: the formula for each security that defines the interest rate paid to investors in the event of a failed auction; forward projections of the interest rate benchmarks specified in such formulas; the likely timing of principal repayments; the probability of full repayment considering the guarantees by the U.S. Department of Education of the underlying student loans and additional credit enhancements provided through other means; and, publicly available pricing data for student loan asset-backed securities that are not subject to auctions. Our estimate of the rate of return required by investors to own these securities also considers the reduced liquidity for auction-rate securities. To date, we have collected all interest on all of our auction-rate securities when due and expect to continue to do so in the future.

Valuation of debt and equity investments and certain liabilities (Policies)	9 Months Ended
	Sep. 30, 2011
Valuation of debt and equity investments and certain liabilities [Abstract]
Investment policy	We classify our investments as available-for-sale, trading, equity method or cost method. Most of our investments are classified as available-for-sale. Available-for-sale and trading securities are stated at fair value, which is generally based on market prices, broker quotes or, when necessary, financial models (see fair value discussion below). Unrealized gains and losses on available-for-sale securities are recorded as an increase or decrease, net of taxes, in AOCI. We record other-than-temporary losses (impairments) on available-for-sale securities in OI&E. Changes in the fair value of debt securities classified as trading securities are recorded in OI&E. We classify certain mutual funds as trading securities. These mutual funds hold a variety of debt and equity investments intended to generate returns that offset changes in certain deferred compensation liabilities. We record changes in the fair value of these mutual funds and the related deferred compensation liabilities in selling, general and administrative expense. Our other investments are not measured at fair value but are accounted for using either the equity method or cost method. These investments consist of interests in venture capital funds and other non-marketable equity securities. Gains and losses from equity method investments are reflected in OI&E based on our ownership share of the investee’s financial results. Gains and losses on cost method investments are recorded in OI&E when realized or when an impairment of the investment’s value is warranted based on our assessment of the recoverability of each investment.
Fair values of Financial Instruments	Fair Values of Financial Instruments — The fair values of our derivative financial instruments were not significant at September 30, 2011. Our investments in cash equivalents, short-term investments and certain long-term investments are carried at fair value and are discussed in Note 8. The carrying values for other current financial assets and liabilities, such as accounts receivable and accounts payable, approximate fair value due to the short maturity of such instruments. The fair value of our long-term debt approximates the carrying value. Fair value We measure and report our financial assets and certain liabilities at fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The three-level hierarchy discussed below indicates the extent and level of judgment used to estimate fair value measurements. Level 1 — Uses unadjusted quoted prices that are available in active markets for identical assets or liabilities as of the reporting date. Level 2 — Uses inputs other than Level 1 that are either directly or indirectly observable as of the reporting date through correlation with market data, including quoted prices for similar assets and liabilities in active markets and quoted prices in markets that are not active.

Level 3 — Uses inputs that are unobservable, supported by little or no market activity and reflect the use of significant management judgment.

- Definition

Disclosure of accounting policy for investments in financial assets, including marketable securities (debt and equity securities with readily determinable fair values), investments accounted for under the equity method and cost method, securities borrowed and loaned, and repurchase and resale agreements. For marketable securities, the disclosure may include the entity's accounting treatment for transfers between investment categories and how the fair values for such securities are determined. Also, for all investments, an entity may describe its policy for assessing, recognizing and measuring impairment of the investment.

Contingencies (Policies)	9 Months Ended
Contingencies (Policies)	Sep. 30, 2011
Commitments and Contingencies Disclosure [Abstract]
Warranty Costs and Product Liabilities Policy	We routinely sell products with an intellectual property indemnification included in the terms of sale. Historically, we have had only minimal, infrequent losses associated with these indemnities. Consequently, we cannot reasonably estimate or accrue for any future liabilities that may result. We accrue for known product-related claims if a loss is probable and can be reasonably estimated. During the periods presented, there have been no material accruals or payments regarding product warranty or product liability. Historically, we have experienced a low rate of payments on product claims. Although we cannot predict the likelihood or amount of any future claims, we do not believe they will have a material adverse effect on our financial condition, results of operations or liquidity. Consistent with general industry practice, we enter into formal contracts with certain customers that include negotiated warranty remedies. Typically, under these agreements, our warranty for semiconductor products includes: three years coverage; an obligation to repair, replace or refund; and a maximum payment obligation tied to the price paid for our products. In some cases, product claims may exceed the price of our products. From time to time, we also negotiate contingent consideration payment arrangements associated with certain acquisitions, which are recorded at fair value. We are subject to various legal and administrative proceedings. Although it is not possible to predict the outcome of these matters, we believe that the results of these proceedings will not have a material adverse effect on our financial condition, results of operations or liquidity.
