Function : Quad 2-input multiplexer
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 74HC/HCT157 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.
