Part Number : 74HC157
Function : Quad 2-input multiplexer
Package : DIP, SOP 16 Pin Type
Maker : 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 74HC157 / 74HCT157 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.
1. Low-power dissipation
2. Complies with JEDEC standard no. 7A
3. Input levels:
(1) For 74HC157: CMOS level
(2) For 74HCT157: TTL level
4. Non-inverting data path
