74F251A
8-Input Multiplexer with 3-STATE Outputs
General Description
The 74F251A 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 a universal
function generator to generate any logic function of four
variables. Both assertion and negation outputs are pro-
vided.
