Overview

74HC157; 74HCT157 Quad 2-input multiplexer Rev.
8 — 28 December 2015 Product data sheet 1.
General description 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 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 74HC/HCT157.
The state of the common data...
