74AHC123A; 74AHCT123A

Dual retriggerable monostable multivibrator with reset

Rev. 02 — 18 January 2008

Product data sheet

1. General description

The 74AHC123A; 74AHCT123A 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 74AHC123A; 74AHCT123A are dual retriggerable monostable multivibrators with

output pulse width control by three methods. The basic pulse time is programmed by

selection of an external resistor (R

EXT

) and capacitor (C

EXT

). The external resistor and

capacitor are normally connected as shown in

Figure 11.

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.

An internal connection from nRD to the input gate makes it possible to trigger the circuit by

a positive-going signal at input nRD as shown in

Table 3. Figure 8

and

Figure 9

illustrate

pulse control by retriggering and early reset. The basic output pulse width is essentially

determined by the value of the external timing components R

EXT

and C

EXT

. When

EXT

≥

10 nF, the typical output pulse width is deﬁned as: t

= R

EXT

where

= pulse width in ns; R

EXT

= external resistor in kΩ; C

EXT

= external capacitor in pF.

Schmitt-trigger action at all inputs makes the circuit highly tolerant to slower input rise and

fall times. The 74AHC123A; 74AHCT123A is identical to the 74AHC423; 74AHCT423 but

can be triggered via the reset input.

2. Features

All inputs have a Schmitt-trigger action

Inputs accept voltages higher than V

DC triggered from active HIGH or active LOW inputs

Retriggerable for very long pulses up to 100 % duty factor

Direct reset terminates output pulse

For 74AHC123A only: operates with CMOS input levels

For 74AHCT123A only: operates with TTL input levels

ESD protection:

HBM JESD22-A114E exceeds 2000 V

MM JESD22-A115-A exceeds 200 V

CDM JESD22-C101C exceeds 1000 V

Multiple package options

−40 °C

to +85

°C

and from

−40 °C

to +125

°C
