Theory of Operation (Continued)
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
CC by turning on transistor Q1 5. When the
voltage on the capacitor reaches V
REF2, the reset latch 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 de-
tected on the Clear input, the output pulse T can be made
significantly
shorter
