555 Timer Internal Block Diagram. The ic 555 uses three resisters of 5kω therefore the name is given as ic555. In this circuit we have four basic blocks these are 1.
This block diagram gives all the ideas we need for our further discussion of timer ic 555 it contains a voltage divider two comparators rs flip flops and an npn transistor. In most applications the control input is not used so that the control voltage equals 2 3 v cc. A simplified block diagram representing the internal circuitry of the 555 timer is given below with a brief explanation of each of its connecting pins to help provide a clearer understanding of how it works.
