General Description
The ’F251A is a high-speed 8-input digital multiplexer. It pro-
vides, in one package, the ability to select one bit of data
from up to eight sources. It can be used as a universal func-
tion generator to generate any logic function of four vari-
ables. Both assertion and negation outputs are provided.
