What is duty cycle of 555 timer?
The 555 oscillator now produces a 50% duty cycle as the timing capacitor, C1 is now charging and discharging through the same resistor, R2 rather than discharging through the timers discharge pin 7 as before.
How many comparators are used in IC 555 timer?
A 555 timer has two comparators, which are basically 2 op-amps), an R-S flip-flop, two transistors and a resistive network. Resistive network consists of three equal resistors and acts as a voltage divider.
What is bistable mode?
A Bistable multivibrator is a type of circuit which has two stable states (high and low). It stays in the same state until and unless an external trigger input is applied. Generally, a bistable multivibrator stays low until a trigger signal is applied and it stays high until a reset signal is applied.
