FAST AND LS TTL DATA

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:

Z = E
