MM74HC123A

Dual Retriggerable Monostable Multivibrator

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

General Description

PW 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.

The MM74HC123A high speed monostable multivibrators

(one shots) utilize advanced silicon-gate CMOS technol-

ogy. They feature speeds comparable to low power Schot-

tky TTL circuitry while retaining the low power and high

noise immunity characteristic of CMOS circuits.

Features

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 MM74HC123A

can be triggered on the positive transition of the clear while

A is held LOW and B is held HIGH.

■ Typical propagation delay: 25 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

■ Simple pulse width formula T = RC

■ Wide pulse range: 400 ns to ∞ (typ)

■ Part to part variation: ±5% (typ)

The MM74HC123A is retriggerable. That is it may be trig-

gered 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 achieved using linear CMOS techniques. The out-

■ Schmitt Trigger A & B inputs enable infinite signal input

rise and fall times.
