This article describes the One Shot Multivibrator / Timer (LM139). The principle is very simple, very practical. The circuit components can help you understand better grasp this principle. For example, in this circuit, you can go to find and buy these components: LM139.

One shot multivibrator circuit is also known as monostable multivibrator or timer. The function of such circuit is simply produce a pulse strobe with a fixed width, regardless of the pulse width of the triggering input.? Below is the circuit’s schematic diagram of simple one shot multivibrator uses one section of an LM139 comparator. The width of the output pulse is set by C2/R4. Input trigger amplitude is set by R1/R2.
