MM74HC123A - Dual Retriggerable Monostable Multivibrator

Download the MM74HC123A datasheet PDF. This datasheet also covers the MM74HC123AJ variant, as both devices belong to the same dual retriggerable monostable multivibrator family and are provided as variant models within a single manufacturer datasheet.

General Description

The MM54 74HC123A high speed monostable multivibrators (one shots) utilize advanced silicon-gate CMOS technology They feature speeds comparable to low power Schottky TTL circuitry while retaining the low power and high noise immunity characteristic of CMOS circuits Each multivibrator

Key Features

  • both a negative A and a positive B transition triggered input either of which can be used as an inhibit input Also included is a clear input that when taken low resets the one shot The ’HC123 can be triggered on the positive transition of the clear while A is held low and B is held high The ’HC123A is retriggerable That is it may be triggered repeatedly while their outputs are generating a pulse and the pulse will be extended Pulse width stability over a wide range of temperature and supply is a.
