description/ordering information
These edge-triggered multivibrators feature
output pulse-duration control by three methods. In
the first method, the A input is low, and the B input
goes high. In the second method, the B input is
high, and the A input goes low. In the third method,
the A input is low, the B input is high, and the clear
(CLR) input goes high.
The output pulse
duration
is programmed by
selecting external resistance and capacitance
values. The external timing capacitor must be
connected between C
ext
and R
ext
/C
ext
(positive)
and an external resistor connected between
R
ext
/C
ext
and V
CC
. To obtain variable pulse
durations, connect an external variable resistance
between R
ext
/C
ext
and V
CC
. The output pulse
duration also can be reduced by taking CLR low.
