MICROCIRCUIT DATA SHEET Original Creation Date: 06/25/97 Last Update Date: 07/08/97 Last Major Revision Date: 06/25/97 CN54F251A-X REV 0A0 8-INPUT MULTIPLEXER WITH TRI-STATE OUTPUTS General Description The F251A 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. It can be used as a universal function generator to generate any logic function of four variables. Both assertion and negation outputs are provided.
