74HC123; 74HCT123

Dual retriggerable monostable multivibrator with reset

Rev. 05 — 13 July 2009

Product data sheet

1. General description

The 74HC123; 74HCT123 are high-speed Si-gate CMOS devices and are pin compatible

with Low-power Schottky TTL (LSTTL). They are speciﬁed in compliance with JEDEC

standard no. 7A.

The 74HC123; 74HCT123 are dual retriggerable monostable multivibrators with output

pulse width control by three methods:

1. The basic pulse is programmed by selection of an external resistor (R

EXT

) and

capacitor (C

EXT

2. Once triggered, the basic output pulse width may be extended by retriggering the

gated active LOW-going edge input (nA) or the active HIGH-going edge input (nB). By

repeating this process, the output pulse period (nQ = HIGH, nQ = LOW) can be made

as long as desired. Alternatively an output delay can be terminated at any time by a

LOW-going edge on input nRD, which also inhibits the triggering.

3. An internal connection from nRD to the input gates makes it possible to trigger the

circuit by a HIGH-going signal at input nRD as shown in the function table.

Schmitt-trigger action in the nA and nB inputs, makes the circuit highly tolerant to slower

input rise and fall times.

The 74HC123; 74HCT123 are identical to the 74HC423; 74HCT423 but can be triggered

via the reset input.

2. Features

DC triggered from active HIGH or active LOW inputs

Retriggerable for very long pulses up to 100 % duty factor

Direct reset terminates output pulse

Schmitt-trigger action on all inputs except for the reset input

ESD protection:

HBM JESD22-A114E exceeds 2000 V

MM JESD22-A115-A exceeds 200 V

Speciﬁed from

−40 °C

to +85

°C

and from

−40 °C

to +125

°C
