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
Features
Y High speed operation input repetition rate l 10 MHz
Y Flexibility of operation optional retriggering lock-out
capability
Y Output pulse width range 50 ns to %
Y Leading or trailing edge triggering
Y Complementary outputs inputs
Y Input clamping diodes
Y DTL TTL compatible logic levels
Y Alternate Military Aerospace device (9601) is available
