74HC423; 74HCT423

Dual retriggerable monostable multivibrator with reset

Rev. 03 — 24 July 2008

Product data sheet

1. General description

74HC423; 74HCT423 are high-speed Si-gate CMOS devices that are pin compatible with

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

standard no. 7A.

The 74HC423; 74HCT423 dual retriggerable monostable multivibrator with reset has two

methods of output pulse width control.

1. The minimum pulse width is essentially determined by the selection of an external

resistor (R_EXT) and capacitor (C_EXT), see Section 12.1.

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. When nRD is LOW, it forces the nQ output LOW, the nQ output

HIGH and also inhibits the triggering. Figure 10 and Figure 11 illustrate pulse control

by reset.

The nA and nB inputs’ Schmitt trigger action makes them highly tolerant to slower input

rise and fall times.

The 74HC423; 74HCT423 are identical to the 74HC123; 74HCT123 except that they

cannot be triggered via the reset input.

2. Features

I DC triggered from active HIGH or active LOW inputs

I Retriggerable for very long pulses up to 100% duty factor

I Direct reset terminates output pulse

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

I Complies with JEDEC standard no. 7A

I ESD protection:

N HBM JESD22-A114E exceeds 2000 V

N MM JESD22-A115-A exceeds 200 V

I Speciﬁed from −40 °C to +85 °C and from −40 °C to +125 °C
