74AHC157; 74AHCT157

Quad 2-input multiplexer

Rev. 02 — 9 November 2007

Product data sheet

1. General description

The 74AHC/AHCT157 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 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. 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 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

2Y = E

(2I1

S + 2I0

3Y = E

(3I1

S + 3I0

4Y = E

(4I1

S + 4I0

The 74AHC/AHCT157 is identical to the 74AHC/AHCT158 but has non-inverting (true)

outputs.

2. Features

Balanced propagation delays

All inputs have a Schmitt-trigger action

Inputs accepts voltages higher than V

Multiple input enable for easy expansion

Ideal for memory chip select decoding

For 74AHC157 only: operates with CMOS input levels

For 74AHCT157 only: operates with TTL input levels

ESD protection:

HBM JESD22-A114E exceeds 2000 V

MM JESD22-A115-A exceeds 200 V

CDM JESD22-C101C exceeds 1000 V
