1 / 5 page © 2000 Fairchild Semiconductor Corporation DS006539 www.fairchildsemi.com August 1986 Revised March 2000 DM74123 Dual Retriggerable One-Shot with Clear and Complementary Outputs General Description 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. 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. Features s DC triggered from active-HIGH transition or active-LOW transition inputs s Retriggerable to 100% duty cycle s Direct reset terminates output pulse s Compensated for VCC and temperature variations s DTL, TTL compatible s Input clamp diodes Ordering Code: Connection Diagram Triggering Truth Table H = HIGH Voltage Level L = LOW Voltage Level X = Immaterial Functional Description The basic output pulse width is determined by selection of 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 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.
