It is one of the handiest ICs to be invented and specially designed to operate as a multivibrator. It is a TTL device. So, It is not sensitive to static electricity. So, we must attend especially to this point, when designing for battery operation. When operating as an oscillator, we can consider the power consumed to be equal to that of a LED. When the price falls it will be a very good choice as it consumes only 120uA. Read next: Monostable multivibrator using 555 timer To date, there are many limitations such as output current capability maximum voltage levels on the triggering pins. Features Can accurate time delays or oscillation Direct replacement for SE555NE555 Timing from microseconds through hours Operates in both astable and monostable modes Adjustable duty cycle Output can source or sink up to 200 mA Output and supply TTL compatible. Such as, With a 5-V supply, output levels are compatible with TTL inputs. Ne555 Timer Circuit Schematic Generator Recommended OperatingTemperature stability better than 0.005 per C Normally on and normally OFF the output Available in 8-pin MSOP package Applications Pulse generation Time delay generation Sequential timing Precision timing Pulse width modulation Pulse position modulation Linear ramp generator Recommended Operating Conditions See the details of NE555 on the operating free-air temperature range. VCC the supply voltage: 4.5V to 16V Vi the input voltages(all): VCC Io the output current: 200mA TA Operating free-air temperature: 0 70C Read related: AC dimmer for LED Bulbs using IC-555 555 pinout The 555 timers are contained in a tiny 8 pin Dual-In-Line package look like a 741 op-amp or LM386 audio amplifier. Also: 555 Siren sound Generator Full 555 schematic Look at the circuit diagram. Ne555 Timer Circuit Schematic Full Schematic DiagramThis full schematic diagram is mainly to show its complexity. Obviously it would not be worthwhile making this circuit from the normal components. It incorporates 28 transistors and a set of resistors housed inside the 8 pin package. In addition, if you like to learn electronics from transistor circuits You can see more. The Three Fives Discrete 555 Timer kit from Evil Mad Scientist Laboratories is a faithful and functional transistor scale replica of the classic NE555 timer integrated circuit.

In this diagram, you can see a free-running flip-flop which is triggered via pins 2 and 6 to drive the output pin 3. The 555 timer can provide time delays ranging from several minutes for one cycle of operation to many thousands of cycles per second. Read next: 555 Sound effect generator circuit Any circuit which cycles more than a few times per second is called an oscillator. The frequency of oscillation is measured in cycles per second(cps) now called Hertz(Hz). Pin 2- Trigger. It will detect the 13 of the supply voltage.
