MOTOROLA MC74F151

MC54/74F151
8-INPUT MULTIPLEXER
The MC54/74F151 is a high-speed 8-input digital multiplexer. It provides in
one package, the ability to select one line of data from up to eight sources. The
F151 can be used as a universal function generator to generate any logic
function of four variables. Both asserted and negated outputs are provided.
The F151 is a logic implementation of a single pole, 8-position switch with
the switch position controlled by the state of three Select inputs, S0, S1, S2.
The Enable input (E) is active LOW. The logic function provided at the output
is:
