MM54HC123A Datasheet PDF (Dual Retriggerable Monostable Multivibrator)

MM54HC123A - Dual Retriggerable Monostable Multivibrator

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

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.
