Typical Applications
(Continued)
The circuit shown above provides output signals at a pre-
scribed time interval from a time reference and automatically
resets the output when the input returns to ground. Consider
the case of V
= 0. The output of comparator 4 is also at
ground. This implies that the outputs of comparators 1, 2,
and 3 are also at ground. When an input signal is applied,
the output of comparator 4 swings high and C charges expo-
nentially through R. This is indicated above.
The output voltages of comparators 1, 2, and 3 switch to the
high state when V
rises above the reference voltage V
A
,
V
and V
. A small amount of hysteresis has been provided
to insure fast switching when the RC time constant is chosen
to give long delay times.
