9602/DM9602 Dual Retriggerable, Resettable One Shots
June 1989
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.

Note:
The ‘‘Absolute Maximum Ratings’’ are those values
beyond which the safety of the device cannot be guaran-
teed. The device should not be operated at these limits. The
parametric values defined in the ‘‘Electrical Characteristics’’
table are not guaranteed at the absolute maximum ratings.
The ‘‘Recommended Operating Conditions’’ table will define
the conditions for actual device operation.

Operating Rules
TL/F/6611–3
1. An external resistor (R
X
) and external capacitor (C
X
) are
required as shown in the Logic Diagram.
2. The value of C
X
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:

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.
