The name 555 comes from the fact that it contains three 5 Kilo-Ohm resistors in series to form the voltage divider pattern.It can be used either as a pulse generator or an oscillator by operating it in different modes.
it can be operated of different power supplies ranging from 5 Volts to 18 Volts. While NE 555 timer can be used in the temperature range from 0 to 70☌, the SE 555 Timer can be used in the temperature range from -55☌ to 125☌ and has a temperature stability of 0.005% per 0C. There are two types of 555 timer based on its nomenclature – NE 555 Timer and SE 555 Timer. Binary Decoder – Construction, Types & Applications. Binary Encoder – Construction, Types & Applications. It may provide time delay from microseconds up to many hours.ĥ55 timer is a very cheap IC which works for wide range of potential difference (typically, from 4.5 to 15V DC) and the different provided input voltages do not affect the timer output. It was developed in the year 1970 by Signetic Corporation and designed by Hans Camenzind in 1971.ĥ55 Timer is a versatile and most usable device in the electronics circuits and designs which work for both stable and monostable states. In more simple words, 555 Timer is a monolithic timing circuit, which can produce accurate timing pulses with 50% or 100% duty cycle. In other words, 555 Timer is a circuit which may be connected as a stable or monostable multivibrator.

In other words, those circuits, which work on the base of multivibrator changes or a device, which can be used as multivibrator is called Timer. Timers are those circuits, which provide periodic signals to a digital system which change the state of that system. Schematic & Working Principle of 555 Timer IC.
