Typical Applications
One-Shot Multivibrator
Figure 30. One-Shot Multivibrator
A monostable multivibrator has one stable state in which it can remain indefinitely. It can be triggered externally
to another quasi-stable state. A monostable multivibrator can thus be used to generate a pulse of desired width.
The desired pulse width is set by adjusting the values of C
2
and R
4
. The resistor divider of R
1
and R
2
can be
used to determine the magnitude of the input trigger pulse. The LMC6762 will change state when V
1
< V
2
. Diode
D
2
provides a rapid discharge path for capacitor C
2
to reset at the end of the pulse. The diode also prevents the
non-inverting input from being driven below ground.
Bi-Stable Multivibrator
Figure 31. Bi-Stable Multivibrator
A bi-stable multivibrator has two stable states. The reference voltage is set up by the voltage divider of R
2
and
R
3
. A pulse applied to the SET terminal will switch the output of the comparator high. The resistor divider of R
1
,
R
4
, and R
5
now clamps the non-inverting input to a voltage greater than the reference voltage. A pulse applied to
RESET will now toggle the output low.
