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

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

X
and an external capacitor C

are
required for operation The value of R
X
can vary between
the limits shown in switching characteristics The value of
C
X
is optional and may be adjusted to achieve the re-
quired output pulse width
