description
The ’LV123A devices are dual retriggerable
monostable multivibrators designed for 2-V to
5.5-V V
CC
operation.
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 programmable 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 can also be reduced by taking CLR low.
Pulse triggering occurs at a particular voltage level and is not directly related to the transition time of the input
pulse. The A, B, and CLR inputs have Schmitt triggers with sufficient hysteresis to handle slow input transition
rates with jitter-free triggering at the outputs.
