MC74ACT157
Quad 2 Input Multiplexer
The MC74AC157/74ACT157 is a high-speed quad 2-input multiplexer. Four
bits of data from two sources can be selected using the common Select and Enable
inputs. The four outputs present the selected data in the true (noninverted) form.
The MC74AC157/74ACT157 can also be used as a function generator.

MC74AC157 MC74ACT157
FUNCTIONAL DESCRIPTION
The MC74AC157/74ACT157 is a quad 2-input multiplexer.
It selects four bits of data from two sources under the control
of a common Select input (S). The Enable input (E) is
active-LOW. When E is HIGH, all of the outputs (Z) are forced
LOW regardless of all other inputs. The MC74AC157/
74ACT157 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. The logic equations for
the outputs are shown below:
Za = E

•

A common use of the MC74AC157/74ACT157 is the
moving of data from two groups of registers to four common
output busses. The particular register from which the data
comes is determined by the state of the Select input. A less
obvious use is as a function generator. The MC74AC157/
74ACT157 can generate any four of the sixteen different
functions of two variables with one variable common. This is
useful for implementing gating functions.
