8-Input Multiplexer with TRI-STATE Outputs
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
Features
