Description

   The DM74123 is a dual retriggerable monostable multivibrator capable of generating output pulses from a few nano-seconds to extremely long duration up to 100% duty cycle. Each DM74122 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 triggering. An internal connection from CLR to the input gate makes DM74122 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 OneShot Application Notes carefully and observe recommendations.
