                            EXPLANATORY STATEMENT

A total of 4,000,000 shares of common stock of Texas Instruments Incorporated 
("the Company") were registered by Registration Statement on Form S-8, File 
No. 33-21407, to be issued in connection with the TI Employees 1988 Stock 
Option Purchase Plan (the "1988 Plan").  On April 17, 1997, the stockholders 
of the Company approved the TI Employees 1997 Stock Purchase Plan (the "1997 
Plan"), which replaces the 1988 Plan.  Both the 1988 Plan and the 1997 Plan 
are intended to qualify as "employee stock purchase plans" under Section 423 
of the Internal Revenue Code of 1986, as amended from time to time.  Two 
million three hundred thousand (2,300,000) shares of common stock of the 
Company which were registered in connection with the 1988 Plan have not been 
issued under the 1988 Plan and, pursuant to Instruction E to Form S-8 and the 
telephonic interpretation of the Securities and Exchange Commission set forth 
at pages 137-38 of the Division of Corporation Finance's Manual of Publicly 
Available Telephone Interpretations (January 1997), are carried forward to, 
and deemed covered by, the Registration Statement of Form S-8 filed on or 
about the date hereof in connection with the 1997 Plan.
