8-Input Multiplexer
General Description
The ’AC/’ACT151 is a high-speed 8-input digital multiplexer.
It provides, in one package, the ability to select one line of
data fromup to eight sources. The ’AC/’ACT151 can be used
as a universal function generator to generate any logic function of four variables. Both true and complementary outputs
are provided.

Functional Description
The ’AC/’ACT151 is a logic implementation of a single pole,
8-position switch with the switch position controlled by the
state of three Select inputs, S
0,S1,S2
. Both true and
complementary outputs are provided. TheEnable input(E) is
active LOW. When it is not activated, the complementary
output is HIGH and the true output is LOW regardless of all
other inputs. The logic function provided at the output is:
