Cell libraries mix 3- and 5-V elements

Cell libraries mix 3- and 5-V elements

A production-ready process allows cells from 5- and 3-V libraries to be
mixed, with 5 V used in critical paths, and 3 V used to save power
elsewhere; 3-V speeds reach 70 MHz, and 5-V speeds reach 100 MHz.
Translator cells couple the two voltages internally. AT&T
