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 (REXT and CEXT).  
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  
For 74AHCT123A: TTL level  
ESD protection:  
HBM JESD22-A114E exceeds 2000 V  
MM JESD22-A115-A exceeds 200 V  
CDM JESD22-C101C exceeds 1000 V  
Latch-up performance exceeds 100 mA per JESD 78 Class II Level A  
Multiple package options  
Specified from -40 °C to +85 °C and from -40 °C to +125 °C
