Overview
74AC251 • 74ACT251 8-Input Multiplexer with 3-STATE Output November 1988 Revised November 1999 74AC251 • 74ACT251 8-Input Multiplexer with 3-STATE Output General Description The AC/ACT251 is a high-speed 8-input digital multiplexer.
It provides, in one package, the ability to select one bit of data from up to eight sources.
It can be used as universal function generator to generate any logic function of four variables.
Both true and complementary outputs are provided.
