Overview

MM74HC423A Dual Retriggerable Monostable Multivibrator September 1983 Revised February 1999 MM74HC423A Dual Retriggerable Monostable.

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 MM74HC423A cannot be triggered from clear. The MM74HC423A is retriggerable. That is, it may be triggered repeatedly while its outputs are generating a pulse and the pulse will be extended. Pulse width stability over a wide range of temperature and supply is achieved using linear CMOS techniques. The output.
