DM74123  
Dual Retriggerable One-Shot with  
Clear and Complementary Outputs  
General Description  
Features  
■ DC triggered from active-HIGH transition or active-LOW  
The DM74123 is a dual retriggerable monostable multi-  
vibrator capable of generating output pulses from a few  
nano-seconds to extremely long duration up to 100% duty  
cycle. Each device has three inputs permitting the choice of  
either leading-edge or trailing edge triggering. Pin (A) is an  
active-LOW transition trigger input and pin (B) is an active-  
HIGH transition trigger input. A LOW at the clear (CLR)  
input terminates the output pulse: which also inhibits trig-  
gering. An internal connection from CLR to the input gate  
makes it possible to trigger the circuit by a positive-going  
signal on CLR as shown in the Truth Table.  
transition inputs  
■ Retriggerable to 100% duty cycle  
■ Direct reset terminates output pulse  
■ Compensated for VCC and temperature variations  
■ DTL, TTL compatible  
■ Input clamp diodes  
To obtain the best and trouble free operation from this  
device please read the Operating Rules as well as the  
One–Shot Application Notes carefully and observe recom-  
mendations.

Functional Description  
The basic output pulse width is determined by selection of  
transition clear input. Retriggering to 100% duty cycle is  
possible by application of an input pulse train whose cycle  
time is shorter than the output cycle time such that a con-  
tinuous “HIGH” logic state is maintained at the “Q” output.  
an external resistor (RX) and capacitor (CX). Once trig-  
gered, the basic pulse width may be extended by retrigger-  
ing the gated active-LOW transition or active-HIGH  
transition inputs or be reduced by use of the active-LOW
