Texas Instruments announced the acquisition of National Semiconductor is complete. More than 5,000 National employees will immediately become part of TI. The two companies will begin the work to integrate National as a unit of TI’s Analog business, which will have a combined portfolio of nearly 45,000 analog products, customer design tools, and a sales force that is 10 times larger than National’s previous footprint.

The transaction, announced on April 4, 2011, cleared all required regulatory reviews and was approved by National’s shareholders. TI will include National’s contribution to financial performance in the company’s third-quarter earnings announcement on October 24. With today’s close, TI’s Analog semiconductor business now represents more than 50 percent of the company’s revenue.

TI will continue to operate National’s manufacturing sites, located in Maine, Scotland and Malaysia, as well as business headquarters in Santa Clara and sales/design support around the world.
