54F/74F151A 8-Input Multiplexer November 1994 54F/74F151A 8-Input Multiplexer General Description The ’F151A is a high-speed 8-input digital multiplexer. It pro- vides in one package the ability to select one line of data from up to eight sources. The ’F151A can be used as a universal function generator to generate any logic function of four variables. Both assertion and negation outputs are provided.

Both assertion and nega- tion outputs are provided. The Enable input (E ) is active LOW. When it is not activated, the negation output is HIGH and the assertion output is LOW regardless of all other in- puts. The logic function provided at the output is: Z e E # (I0 S2 S1 S0 a I1 S2 S1 S0 a I2 S2 S1 S0 a I3 S2 S1 S0 a I4 S2 S1 S0 a I5 S2 S1 S0 a I6 S2 S1 S0 a I7 S2 S1 S0) The ’F151A provides the ability, in one package, to select from eight sources of data or control information. By proper manipulation of the inputs, the ’F151A can provide any logic function of four variables and its negation.
