Monostable Multivibrator using 555 Timer Explained (with Working, Applications and Derivation)

In this video, it has been explained that how 555 timer can be configured to use as a monostable multivibrator. The working of the circuit is explained using the internal block diagram and timing diagram.

And at the end of the video, the expression for calculating the time delay is also derived.

By watching this video, you will learn the following topics.

1:32 Design of Monostable Multivibrator using 555 timer IC (Circuit Diagram)

2:15 Working of Monostable Multivibrator

8:44 Applications of Monostable Multivibrator

11:03 Derivation of Time-Delay expression for monostable multivibrator

What is Monostable Multivibrator?

The monostable Multivibrator has one stable state. But whenever the trigger signal is applied then momentarily the output goes into the unstable state.
The time duration for which the output goes into the unstable state can be controlled by the external resistor and capacitor.

Whenever this monostable multivibrator is designed using the 555 timer IC then it can be used in the following applications:

1) Generating Time Delays
2) Switching the Relays
3) To generate Pulse Width Modulated (PWM) Output
4) Frequency Division

This video will be helpful to all the students of science and engineering in understanding the design and working of 555 timer as a monostable multivibrator.
