74AHC157 Datasheet – Quad 2-input multiplexer

Part Number : 74AHC157

Function : Quad 2-input multiplexer

Manufacturers : NXP Semiconductors.

Pinouts :

74AHC157 datasheet

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. WhenE is HIGH, all of the outputs (1Y to 4Y) are forced LOW regardless of all other input conditions.
