9601 DM9601 Retriggerable One Shot
June 1989
9601 DM9601 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
