Additional Applications
Figure 19 presents an interesting one-shot which draws no
power supply current until it is triggered.Apositive-going trig-
ger pulse of at least 2V amplitude turns on the amplifier
through R
and pulls the non-inverting input high. The ampli-
fier regenerates and latches its output high until capacitor C
charges to the voltage level on the non-inverting input. The
output then switches low, turning off the amplifier and dis-
charging the capacitor. The capacitor discharge rate is
speeded up by shorting the diode bias pin to the inverting in-
put so that an additional discharge current flows through D
I
when the amplifier output switches low. A special feature of
this timer is that the other amplifier, when biased from V
O
,
can perform another function and draw zero stand-by power
as well.
