555 Timer IC NE555 DIP-8 Precision Timer Chip

This 555 is a very versatile Timer IC that is relatively easy to use. The NE555 timer is an IC that can use to create a variety of timing circuits, such as oscillators, pulse generators, and delays.

The NE555 Timer is an IC that is use in a variety of timer, delay, pulse generation, and oscillator applications. 555 Timer IC is a versatile chip that can use to create a wide range of timing circuits.

The 555 Timer IC monolithic timing circuit is a highly stable controller capable of producing accurate time delays, or oscillation. In the time delay mode of operation, the time is precisely controlled by one external resistor and capacitor.

For a stable operation as an oscillator, the free running frequency and the duty cycle are both accurately controlled with two external resistors and one capacitor. The circuit may be triggered and reset on falling waveforms, and the output structure can source or sink up to 200mA.

The NE555 timer IC can operate with a supply voltage in the range of 4.5 to 16 volts. The input voltage can be anywhere in the supply voltage range, but it is important to note that the input voltage must be greater than the threshold voltage of the NE555, which is typically around 1.7 volts. If the input voltage is less than the threshold voltage, the NE555 will not be able to operate properly.

The NE555 timer IC has two timing resistors and a capacitor that are connected to the trigger, threshold, and output pins. The timing resistors and capacitor determine the length of the timing cycle.

555 TIMER IC can use for temperature ranges between – 55°C to 125 °.

Operating Modes : –

The NE555 timer IC has three operating modes:

• Monostable mode: In monostable mode, the NE555 timer generates a single pulse of a specified duration. The duration of the pulse is determined by the timing resistors and capacitor.
• Astable mode: In astable mode, the NE555 timer generates a square wave of a specified frequency. The frequency of the square wave is determined by the timing resistors and capacitor.
• Bistable mode: In bistable mode, the NE555 timer acts as a flip-flop. The output of the NE555 timer can be either high or low, and it will remain in that state until the trigger input is changed.
