MC74AC157, 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 (non-inverted) form.  
The MC74AC157/74ACT157 can also be used as a function  
generator.

FUNCTIONAL DESCRIPTION

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:  
Z = E•(I •S+I •S)  
d
1d  
0d  
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.
