54AC151/54ACT151 8-Input Multiplexer
General Description
The ’AC/’ACT151 is a high-speed 8-input digital multiplexer. It provides, in one package, the ability to select one line of data from up to eight sources. The ’AC/’ACT151 can be used as a universal function generator to generate any logic function of four variables. Both true and complementary outputs are provided. n ’ACT151 has TTL-compatible inputs n Standard Microcircuit Drawing (SMD) — ’AC151: 5962-87691 — ’ACT151: 5962-88756 n 54AC151 now qualified to 300Krad RHA designation, refer to the SMD for more information
