9601DM9601 Retriggerable One Shot

General Description

These retriggerable one shots provide the designer with

four inputs two active high and two active low This permits

a choice of either leading-edge or trailing-edge triggering

independent of input transition times When input conditons

for triggering are met a new cycle starts and the external

capacitor is rapidly discharged and then allowed to charge

again The retriggerable feature allows for output pulse

widths to be expanded In fact a continuous true output can

be maintained by having an input cycle time which is shorter

than the output cycle time Retriggering may be inhibited by

tying the Q output to an active low input
