11+ Astable Multivibrator Circuit Diagram. The astable multivibrator circuit is a classic circuit for flashing two leds. The astable multivibrator is a really important circuit in electronics.
The astable multivibrator is a really important circuit in electronics. The capacitor c charges via r1 and r2 and when the voltage on the capacitor reaches 2/3 of the supply, pin 6 detects this and pin 7 connects to 0v. In a monostable multivibrator, one of the state is absolutely permanent i.e, stable and the other one is thus a mono stable multivibrator can not generate square wave of its own like an astable figure shows the circuit of a monostable multivibrator using npn transistor.
A multivibrator circuit consists generally of two inverting amplifier stages.

At time t0 transistor q1 is in saturation, and its collector voltage is close to ground. 8th pin and 1st pin of the ic are used to give power, vcc and gnd respectively.
