74AHC157-Q100;  
74AHCT157-Q100  
Quad 2-input multiplexer  
Rev. 1 — 4 July 2013  
Product data sheet  
1. General description  
The 74AHC157-Q100; 74AHCT157-Q100 is a high-speed Si-gate CMOS device and is  
pin compatible with Low-Power Schottky TTL (LSTTL). It is specified in compliance with  
JEDEC standard no. 7A.  
The 74AHC157-Q100; 74AHCT157-Q100 is a quad 2-input multiplexer which selects 4  
bits of data from two sources under the control of a common data select input (S). The  
enable input (E) is active LOW. When E is HIGH, all of the outputs (1Y to 4Y) are forced  
LOW regardless of all other input conditions. Moving the data from two groups of registers  
to four common output buses is a common use of the 74AHC157-Q100;  
74AHCT157-Q100. The state of the common data select input (S) determines the  
particular register from which the data comes. It can also be used as function generator.  
The device is useful for implementing highly irregular logic by generating any four of the  
16 different functions of two variables with one variable common. The 74AHC157-Q100;  
74AHCT157-Q100 is logic implementation of a 4-pole, 2-position switch. The logic levels  
applied to S, determines the position of the switch.  
The logic equations are:  
1Y = E (1I1 S + 1I0 S)  
2Y = E (2I1 S + 2I0 S)  
3Y = E (3I1 S + 3I0 S)  
4Y = E (4I1 S + 4I0 S)  
This product has been qualified to the Automotive Electronics Council (AEC) standard  
Q100 (Grade 1) and is suitable for use in automotive applications.  
2. Features and benefits  
Automotive product qualification in accordance with AEC-Q100 (Grade 1)
