9602 DM9602 Dual Retriggerable
Resettable One Shots
General Description
These dual resettable retriggerable one shots have two in-
puts per function one which is active high and one which is
active low This allows the designer to employ either lead-
ing-edge or trailing-edge triggering which is independent of
input transition times When input conditions for triggering
are met a new cycle starts and the external capacitor is
allowed to rapidly discharge and then charge again The
retriggerable feature permits output pulse widths to be ex-
tended In fact a continuous true output can be maintained
by having an input cycle time which is shorter than the out-
put cycle time The output pulse may then be terminated at
any time by applying a low logic level to the RESET pin
Retriggering may be inhibited by either connecting the Q
output to an active high input or the Q output to an active
low input
Features

Y TTL input gating leading or trailing edge triggering
Y Complementary TTL outputs
Y Optional retrigger lock-out capability
Y Pulse width compensated for VCC and temperature
variations
Y Alternate Military Aerospace device (54xxx) is available
