Ic 555 Multivibrator Circuit. Astable mode monostable mode and bistable mode are the three modes of operation of ic 555. By jayant sep 29 2015 5.
Two resistors r1 and r2 and a capacitor c. Monostable bistable multivibrator. The 74121 is an ic monostable multivibrator with two active low and one active high input trigger sources and an active high and an active low pulse output terminal.
Time period t 1 1rc.

Multivibrator can be designed as shown in the circuit diagram with typical component values using ic 555 for a duty cycle of more than 50. This method can be used to generate clock pulses for microcontrollers digital ic s or blink an led or any other applications where specific time intervals.
