SN74LS251
8-Input Multiplexer
with 3-State Outputs
The TTL/MSI SN74LS251 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 LS251 can be used as a universal
function generator to generate any logic function of four variables.
Both assertion and negation outputs are provided.
