General Description
The ’AC/’ACT158 is a high-speed quad 2-input multiplexer. It
selects four bits of data from two sources using the common
Select and Enable inputs. The four buffered outputs present
the selected data in the inverted form. The ’AC/’ACT158 can
also be used as a function generator.

Functional Description
Truth Table
The ’AC/’ACT158 quad 2-input multiplexer selects four bits
of data from two sources under the control of a common Se-
lect input (S) and presents the data in inverted form at the
four outputs. The Enable input (E) is active-LOW. When E is
HIGH, all of the outputs (Z) are forced HIGH regardless of all
other inputs. The ’AC/’ACT158 is the logic implementation of
a 4-pole, 2-position switch where the position of the switch is
determined by the logic levels supplied to the Select input.

A common use of the ’AC/’ACT158 is the moving of data
from two groups of registers to four common output busses.
The particular register from which the data comes is deter-
mined by the state of the Select input. A less obvious use is
as a function generator. The ’AC/’ACT158 can generate four
functions of two variables with one variable common. This is
useful for implementing gating functions.
