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
, S
1
, S
2
. Both true and
complementary outputs are provided. The Enable 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:

The ’AC/’ACT151 provides the ability, in one package to se-
lect from eight sources of data or control information. By
proper manipulation of the inputs, the ’AC/’ACT151 can pro-
vide any logic function of four variables and its complement.
