Monostable multivibrators, also known as one-shot multivibrators, are a type of electronic circuit that can be used as a timer. They have one stable and one unstable state. The unstable state is caused by a trigger pulse. This state is transient, so the circuit always returns to stability after a fixed time has elapsed.
Generally, monostable multivibrator circuits are composed of two transistors, coupled with one resistor-capacitor network and one resistor network. These networks are what determines the length of time before the circuit returns to its stable state, after being triggered.
What are monostable multivibrators used for? Monostable multivibrators are used to produce a specific timed delay within a circuit. Therefore, they can broadly be used as timers or as pulse detectors in electronic equipment.
Types of monostable multivibrators There are two types of monostable multivibrators:
Retriggerable monostable multivibrators will remain in the unstable state with repeated application of the trigger pulse.
Non-retriggerable monostable multivibrators are unaffected by further trigger pulses, and will remain in the unstable state only for the predetermined period of time.

Description:
The LTC®6993 is a monostable multivibrator (also known
as a “one-shot” pulse generator) with a programmable pulse width of 1μs to 33.6 seconds. The LTC6993 is part of the Timer Blox® family of versatile silicon timing devices. A single resistor, RSET, programs an internal master oscillator frequency, setting the LTC6993’s ...
Description:
The 74LVC1G123 is a single retriggerable monostable multivibrator
with Schmitt trigger inputs. Output pulse width is controlled by three methods. The basic pulse is programmed by selection of an external resistor (REXT) and capacitor (CEXT). Once triggered, the basic output pulse width may be extended by retriggering the gated active ...
