SN54/74LS151

8-INPUT MULTIPLEXER

The TTL/MSI SN54/74LS151 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. The LS151 can be used as a universal function generator to

generate any logic function of four variables. Both assertion and negation

outputs are provided.
