Pin diagram of ic 555 timer.

Ic 555 block diagram and working. Basics and block diagram of timer ic 555 timer ic 555 linear integrated circuits duration. The biasing voltage vcc is divided in three parts through voltage divider using same value of resistors r. How transistors work the learning circuit duration. Internal functional block diagram and working of each block of ic 555 timer.

The 555 timer ic is an integral part of electronics projects. A 555 timer has two comparators which are basically 2 op amps an r s flip flop two transistors and a resistive network. Be it a simple project involving a single 8 bit micro controller and some peripherals or a complex one involving system on chips socs 555 timer working is involved. The following block diagram shows the 555 timer integrated circuit.
