M1D-eCoc7fo-48dAeSCrh/1eDe5et14m,UuM.cloCtmi7p4leAxCeTr 151The MC74AC151/74ACT151 is a high–speed 8–input digital
tamultiplexer. It provides, in one package, the ability to select one line of
data from up to eight sources. The MC74AC151/74ACT151 can be
aused as a universal function generator to generate any logic function of
.Dfour variables. Both true and complementary outputs are provided.
