Texas Instruments bought National Semiconductor in 2011. National stopped being an independent public semiconductor company and became part of TI, with its products and expertise incorporated into TI’s Analog business. The acquisition did not, by itself, mean every National-branded chip was renamed or discontinued.
Did TI buy National Semiconductor?
Yes. Texas Instruments announced the all-cash acquisition on April 4, 2011. The offer was $25 per National Semiconductor share, valuing the transaction at approximately $6.5 billion. TI completed the acquisition on September 23, 2011, according to its closing announcement and SEC filing.
At closing, National continued as a legal corporation but became a wholly owned subsidiary of TI. Each eligible National share converted into the right to receive $25 in cash. For National shareholders, the deal was a cash acquisition—not an exchange of National shares for TI shares.
Why did TI acquire National?
The companies described the deal as a combination of complementary analog businesses. TI brought a broader product range, larger global sales force, and manufacturing scale; National brought analog expertise, a strong industrial-power business, customer design tools, and an established product portfolio. TI said the combined sales force would be ten times larger than National’s previous sales footprint.

#1 Best Overall
The companies’ 2011 announcement placed the deal in the context of a $42 billion analog-semiconductor market in 2010. TI reported $6.0 billion in analog revenue and 14% market share that year; National reported about $1.6 billion in calendar-year revenue and 3% share. These are figures cited by the companies at the time of the announcement, not current market figures.
What changed when the deal closed?
TI folded National into its Analog business rather than maintaining it as an independent semiconductor company. TI’s closing release said more than 5,000 National employees joined TI and that the combined analog portfolio approached 45,000 products. The release also said TI continued operating National manufacturing sites in Maine, Scotland, and Malaysia.

At announcement, the SEC transaction fact sheet cited 30,000 TI analog products and 12,000 National analog products. At closing, TI described the combined portfolio as nearly 45,000 products. Those are company-reported portfolio counts from 2011; they do not establish the present number of products or the current status of any particular device.
Are National Semiconductor chips now TI parts?
National Semiconductor became part of TI, and its analog products became part of TI’s business. That is the useful general answer for someone trying to identify the company behind a legacy National device. It does not establish that every National part number was renamed, kept in production, or replaced by a pin-compatible TI device.

National’s technology and product lines continued under TI ownership, while the independent public company ceased to exist as such. TI chairman, president, and CEO Rich Templeton described the rationale as “strength and growth.” National CEO Don Macleod emphasized combining TI’s greater marketplace scale and global sales force with National’s analog capability, particularly in power management.
