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 pro-
vided.
