IC 555 Timer

The following figure shows the functional diagram of timer IC 555.

As shown in figure IC555 includes two comparators, one RS flip-flop and other few discrete components like transistors, resistors etc.

The biasing voltage (Vcc) is divided in three parts through voltage divider using same value of …

Now as shown in figure, there are eight pins for a 555 Timer IC namely,

1.Ground.

2.Trigger.

3.Output.

4.Reset.

5.Control

6.Threshold.

7.Discharge

8.Power or Vcc

Pin 1. Ground: This pin has no special function what so ever. It is connected to ground as usual. For the timer to function, this …
