Theory of Operation
RESET OPERATION
These one shots may be reset during the generation of the
output pulse. In the reset mode of operation, an input pulse
on clear sets the reset latch and causes the capacitor to be
fast charged to V
the voltage on the capacitor reaches V
will clear and then be ready to accept another pulse. If the

clear input is held LOW, any trigger inputs that occur will be
inhibited and the Q and Q outputs of the output latch will
not change. Since the Q output is reset when an input low
level is detected on the Clear input, the output pulse T can
be made significantly shorter than the minimum pulse width
specification.
