74F151A
8-Input Multiplexer
General Description
The F151A is a high-speed 8-input digital multiplexer. It
provides in one package the ability to select one line of
data from up to eight sources. The F151A can be used as a
universal function generator to generate any logic function
of four variables. Both assertion and negation outputs are
provided.
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
