74AHC123A; 74AHCT123A

Dual retriggerable monostable multivibrator with reset

Rev. 5 — 17 June 2020

Product data sheet

1. General description

The 74AHC123A; 74AHCT123A is a dual retriggerable monostable multivibrator with reset. The

basic output pulse width is programmed by selection of external components (R_EXTand C_EXT).

Once triggered this basic pulse width may be extended by retriggering either of the edge triggered

inputs (nA or (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. Inputs are overvoltage tolerant. This feature allows the use of

these devices as translators in mixed voltage environments.

2. Features and benefits

•

Wide supply voltage range from 2.0 V to 5.5 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

Overvoltage tolerant inputs to 5.5 V

All inputs have a Schmitt-trigger action

High noise immunity

Input levels:

•

For 74AHC123A: CMOS level
