MICROCIRCUIT DATA SHEET Original Creation Date: 06/28/96 Last Update Date: 03/31/97 Last Major Revision Date: 06/28/96 MN54AC251-X REV 1B0 8-Input Multiplexer With TRI-STATE Outputs General Description The AC251 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.
