Quad 2-input multiplex er
Rev. 8 — 28 December 2015 Product data sheet 1. General description The 74HC157; 74HCT157 is a high-speed Si-g ate CMOS device and is pin compatible w ith Low-power Schottky TTL. It is speci fied in compliance with JEDEC standard no. 7A. The 74HC/HCT157 are quad 2-inpu t multiplexers which select 4 bits of d ata 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 re . |

Quad 2-input multiplex er
Rev. 9 — 24 July 2020 Product dat a sheet 1. General description The 74H C157; 74HCT157 is a quad 2-input multip lexer. The device features select (S) a nd enable E inputs. A HIGH on S selects data source 1, a LOW data source 0. A HIGH on E forces all the outputs (1Y to 4Y) LOW. Inputs include clamp diodes. This enables the use of current limitin g resistors to interface inputs to volt ages in excess of VCC. 2. Features and benefits • Wide supply voltage range from 2. 0 V to 6. 0 V • CMOS low power dissipation • High noise immunity †¢ Latch-up performance e . |
