74AHC157-Q100 74AHCT157-Q100 Quad 2-input multiplexer Rev. 2 10 September 2020 Product data sheet 1. General description The 74AHC/AHCT157-Q100 are high-speed Si-gate CMOS devices and are pin compatible with Low Power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A. The 74AHC/AHCT157-Q100 are quad 2-input multiplexer which select 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 74AHC/AHCT157-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 74AHC/AHCT157-Q100 is logic implementation of a 4-pole, 2-position switch, where the position of the switch is determine by the logic levels applied to S. 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.
