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.
