74HC123; 74HCT123  
Dual retriggerable monostable multivibrator with reset  
Rev. 8 — 16 December 2011  
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 (REXT) and  
capacitor (CEXT).  
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 and benefits  
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-A114F exceeds 2000 V  
MM JESD22-A115-A exceeds 200 V  
Specified from 40 C to +85 C and from 40 C to +125 C
