Product Summary

The 74HC423A is a high speed monostable multivibrator (one shot). The 74HC423A utilizes advanced silicon-gate CMOS technology. The 74HC423A features 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 74HC423A cannot be triggered from clear.
