Buy online in India the 555 Timer IC or NE555N at Circuit Uncle – The home for IoT and Embedded components. This is the most classic or legacy timer IC, which is used as clock source for many applications. The standard 555 package includes 25 transistors, 2 diodes, and 15 resistors on a silicon chip installed in an 8-pin dual in-line package (DIP-8). The 555 can be used to provide time delays, as an oscillator, or as a flip-flop element. The 555 has three main operating modes, Monostable, Astable, and Bistable. Each mode represents have different circuit layout and a particular output suitable for a specific operation. Some Features of the 555 timer IC (NE555N) are listed below:

Pin Number Pin Name Pin Function
1 Ground This is the Ground pin.
2 Trigger Pin 2 is the trigger pin. It is used to start the 555 timers. The trigger is an active low trigger, i.e., the voltage on pin 2 drops to below 1/3 of the supply voltage.
3 Output Pin 3 is the output pin. The output is either high or low.
4 Reset Pin 4 is the reset pin. This pin can be used to restart the 555 timer operation.
5 Control Voltage Pin 5 is the control pin. In most 555 timer circuits, this pin is simply connected to ground, usually through a small capacitor, about 0.01 µF capacitor.
6 Threshold Pin 6 is the threshold pin. The purpose of this pin is to monitor the voltage across the capacitor that’s discharged by pin 7. When this voltage reaches 2/3 of the supply voltage (Vcc), the timing cycle ends, and the output on pin 3 goes low.
7 Discharge Pin 7 is the discharge pin. This pin is used to discharge an external capacitor that works in conjunction with a resistor to control the timing interval.
8 Power Supply (Vcc) Pin 8 is connected to the positive power supply voltage.
The voltage must be at least 4.5V and no greater than 15V. Using 4 AA or AAA batteries for 6V or a single 9V battery.
