8-Input Multiplexer with TRI-STATE Outputs

Features

General Description

Multifunctional capability

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.
