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 70 ns to % output width range
Y Resettable and retriggerable 0% to 100% duty cycle
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

Operating Rules
1 An external resistor (RX) and external capacitor (CX) are
required as shown in the Logic Diagram
2 The value of CX may vary from 0 to any necessary value
available If however the capacitor has leakages ap-
proaching 3 0 mA or if stray capacitance from either ter-
minal to ground is more than 50 pF the timing equations
may not represent the pulse width obtained
3 The output pulse with (t) is defined as follows

for K vs CX see Figure 6
TL F 6611 – 3
4 If electrolytic type capacitors are to be used the following
three configurations are recommended
A Use with low leakage capacitors
The normal RC configuration can be used predictably
only if the forward capacitor leakage at 5 0V is less
than 3 mA and the inverse capacitor leakage at 1 0V is
less than 5 mA over the operational temperature
range
