Functional Description  
The ’AC/’ACT157 is a quad 2-input multiplexer. It selects  
four bits of data from two sources under the control of a com-  
mon Select input (S). The Enable input (E) is active-LOW.  
When E is HIGH, all of the outputs (Z) are forced LOW re-  
gardless of all other inputs. The ’AC/’ACT157 is the logic  
implementation of a 4-pole, 2-position switch where the posi-  
tion of the switch is determined by the logic levels supplied to  
the Select input. The logic equations for the outputs are  
shown below:  
of the sixteen different functions of two variables with one  
variable common. This is useful for implementing gating  
functions.

A common use of the ’AC/ACT157 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 ’AC/’ACT157 can generate any four
