MM74HC423A

Dual Retriggerable Monostable Multivibrator

General Description

Features

The 74HC423A 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.

■ Typical propagation delay: 40 ns

■ Wide power supply range: 2V–6V

■ Low quiescent current: 80 µA maximum (74HC Series)

■ Low input current: 1 µA maximum

■ Fanout of 10 LS-TTL loads

Each multivibrator features both a negative, A, and a posi-

tive, 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.

■ Simple pulse width formula T = RC

■ Wide pulse range: 400 ns to ∞ (typ)

■ Part to part variation: ±5% (typ)

■ Schmitt Trigger A & B inputs allow rise and fall times to

be as slow as one second

The MM74HC423A is retriggerable. That is, it may be trig-

gered 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 out-

put pulse equation is simply: PW = (R_EXT) (C_EXT); where

is in seconds, R is in ohms, and C is in farads. All inputs

are protected from damage due to static discharge by

diodes to V_CCand ground.
