What is astable multivibrator mode of 555 timer IC?
Astable Multivibrator using 555 Timer | Circuit, Duty Cycle, Applications The 555 Timer IC can be used in a variety of circuits like Time Delays, Oscillation, Pulse Generation, Pulse Width Modulation etc. Now, we will learn about the Astable Multivibrator Mode of 555 Timer IC. We will learn the circuit of Astable Multivibrator using 555 Timer IC, its operation, calculate the duty cycle and also take a look at few important applications of Astable Mode of 555 Timer IC. Astable Multivibrator Mode of 555 Timer IC: Astable multivibrator is also called as Free Running Multivibrator. It has no stable states and continuously switches between the two states without application of any external trigger. The IC 555 can be made to work as an astable multivibrator with the addition of three external components: two resistors (R 1 and R 2 ) and a capacitor (C). The schematic of the IC 555 as an astable multivibrator along with the three external components is shown below. The pins 2 and ...
