## Which of the following is bistable multivibrator?

NAND Gate Bistable Multivibrator This type of bistable circuit is also known as a “Bistable Flip-flop”. The manually controlled bistable multivibrator is activated by the single-pole double-throw switch (SPDT) to produce a logic “1” or a logic “0” signal at the output.

Why is a bistable called a flip-flop?

Bistable Multivibrator is also called flip-flop Multivibrator because, the circuit flips from one state to another state, remains there and flops to it’s original state. These capacitors are known as commutating capacitor and is employed to improve the switching characteristics of the circuit.

### Can a bistable circuit be used with a 555 timer?

In this tutorial, we will show you how to make a Bistable Multivibrator circuit using 555 Timer IC. Bistable multivibrator has two stable states and it remains in the same state until and unless we apply an external trigger to circuit. We also call these circuits as flip-flops and latches.

What are the components of a bistable multivibrator?

The required components of bistable multivibrator using 555 timer IC include IC 555, Resistors, Potentiometer, Capacitors, Diodes 1N 4148, D.C. Power supply, Function Generators, Oscilloscope, Connecting wires and Breadboard. Connect the circuit as per the given circuit diagram. Use resistors RA, RB, RL and capacitors C1, C2.

## Can a 555 timer be used as a flip flop?

So it is commonly used in digital circuits, where it is named as Flip Flop or Latches. A bistable multivibrator can be easily constructed using the most popular and low cost 555 Timer IC. In the above circuit 555 is wired as a bistable multivibrator.

How to calculate on time and off time of 555 multivibrator circuit?

Formula derivation of 555 astable multivibrator. The ON time and OFF time of the astable multivibrator circuit can be calculated by taking the charging and discharging time of the capacitor C. The ON time of a cycle is equal to the charging time of the capacitor from 1/3Vcc to 2/3Vcc and the OFF is equal to the discharge time from 2/3Vcc to 1/3Vcc.
