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

Operating Rules
1 An external resistor RX and an external capacitor CX are
required for operation The value of RX can vary between
the limits shown in switching characteristics The value of
CX is optional and may be adjusted to achieve the re-
quired output pulse width
2 Output pulse width tPW may be calculated as follows

(For CX k 103 pF see curve )
3 RX and CX must be kept as close as possible to the
circuit in order to minimize stray capacitance and noise
pickup If remote trimming is required RX may be split up
such that at least RX(MIN) must be as close as possible
to the circuit and the remote portion of the trimming re-
