Texas Instruments announced that Gilles Delfassy, senior vice president and head of TI’s wireless terminals unit, plans to retire after 28 years with the company. Effective immediately, TI has promoted Greg Delagi to senior vice president and leader of the operation, which develops semiconductors for cell phones. Delfassy, 51, has been at the helm of the company’s wireless terminals unit since its inception in 1995. Delagi, 43, is a 22-year TI veteran who for the past 10 years has led development and commercialization of digital signal processors (DSPs). Delfassy and Delagi will work together over the next six months to ensure an orderly transition.
