Multivibrator Using 555 Timer. The modulating signal is applied at the pin 5 of the first ic 555 that is operating in astable mode. Astable mode monostable mode and bistable mode are the three modes of operation of ic 555.
The 555 timer chip is extremely robust and stable 8 pin device that can be operated either as a very accurate monostable bistable or astable multivibrator to produce a variety of applications such as one shot or delay timers pulse generation led and lamp flashers alarms and tone generation logic clocks frequency division power supplies and converters etc in fact any circuit that requires some form of time control as the list is endless. Astable mode monostable mode and bistable mode are the three modes of operation of ic 555. Astable multivibrator using 555 timer working when the capacitor voltage will becomes slightly greater than 2 3 vcc the output of the higher comparator will be high and of lower comparator will be low.
In this video it has been explained that how 555 timer can be configured to use as a monostable multivibrator.
