Block Diagram of 555 Timer.

. The 555 Timer IC is an 8 pin mini Dual-Inline Package DIP. All the voltages are measured with. The following figure shows the functional diagram of timer IC 555.

The 555 is a monolithic timing circuit that can produce accurate highly stable time delays or oscillation. The key component of the circuit is Thermistor transistor 555 Timer IC and Buzzer. The reference voltages for the a pair of comparators within the 555 are developed around a voltage divider comprising 3 equal resistors of 5K ohms each.

IC 555 block diagram. The output of 555 is used to drive load controlling devices such as transistors and relays. The timer basically operates in one of two modes.

555 Timer ic Tutorial. The significance of each pin is self-explanatory from the above. The pin diagram of a 555 Timer IC is shown in the following figure.

555 timer ic is widely used in many electronics circuits for. The thermistor is a variable resistor its resistance change according to the changing of. The pin numbers of Timer IC 555 and their functions are discussed below.

From the above figure three 5k internal resistors act as voltage divider providing bias voltage of 23 Vcc to the upper comparator 13 Vcc to the lower. The unit includes a pair of comparators a couple of transistors a flip-flop and buffered output stage. A functional block diagram of 555 timer is presented underneath.

555 Timer This is very popular and most common using ic used for various purposes in the electronics area. As shown in figure IC555 includes two comparators one RS flip-flop and other few discrete components like transistors. The block diagram represent the internal connection of 555 is given below.
