The two 10kΩ resistors bias the input to half of the input logic supply level to set the threshold in the mid-point

of the input logic levels. Only one shared output pull-up resistor is needed and can be connected to any pull-up

voltage between 0V and 5.5V. The pullup voltage must match the driven logic input "high" level.

Figure 7-15. One-Shot Multivibrator

A monostable multivibrator has one stable state in which the output can remain indefinitely. The circuit 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 C2 and R4. The resistor divider of R1 and R2 can be

used to determine the magnitude of the input trigger pulse. The output changes state when V1 < V2. Diode D2

provides a rapid discharge path for capacitor C2 to reset at the end of the pulse. The diode also prevents the

non-inverting input from being driven below ground.

Figure 7-16. Bi-Stable Multivibrator

A bi-stable multivibrator has two stable states. The reference voltage is set up by the voltage divider of R2 and

R3. A pulse applied to the SET terminal that sets the output of the comparator high. The resistor divider of R1,

R4, and R5 now clamps the non-inverting input to a voltage greater than the reference voltage. A pulse applied to

RESET toggles the output low.
