Part Number: 74HC157
Function: Quad 2-input Multiplexer
Package: SO16, SSOP 16, TSSOP16, DHVQFN16 Type
Manufacturer: NXP Semiconductors.
The 74HC157, 74HCT157 is a high-speed Si-gate CMOS device and is pin compatible with Low-power Schottky TTL. It is specified in compliance with JEDEC standard no. 7A.
The devices are quad 2-input multiplexers 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 Eis HIGH, all of the outputs (1Y to 4Y) are forced LOW regardless of all other input conditions.
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.
1. Low-power dissipation
2. Complies with JEDEC standard no. 7A
3. Input levels : For 74HC157: CMOS level
4. Non-inverting data path
