Get insight of the product NE555P

NE555P is a precision timing circuit capable of producing accurate time delays or oscillation. In the time-delay or mono-stable mode of operation, the timed interval is controlled by a single external resistor and capacitor network. In the a-stable mode of operation, the frequency and duty cycle can be controlled independently with two external resistors and a single external capacitor.

The threshold and trigger levels normally are two-thirds and one-third, respectively, of VCC. These levels can be altered by the use of the control voltage terminal. When the trigger input falls below the trigger level, the flip-flop is set, and the output goes high. If the trigger input is above the trigger level and the threshold input is above the threshold level, the flip-flop is reset and the output is low. The reset (RESET) input can override all other inputs and can be used to initiate a new timing cycle. When RESET goes low, the flip-flop is reset, and the output goes low. When the output is low, a low-impedance path is provided between discharge (DISCH) and ground.

The output circuit is capable of sinking or sourcing current up to 200 mA. Operation is specified for supplies of 5 V to 15 V. With a 5-V supply, output levels are compatible with TTL inputs.

How to use NE555P?

There are a lot of ways to use the 555 IC. We can use them in hundreds of different circuits to create many clever things. But they can all be put into three groups. In different types of oscillators:

Astable Multivibrator – constantly oscillates

        – For frequencies above 1 cycle per second, it is called an oscillator (multivibrator or square wave oscillator).

  – For frequencies below 1 cycle per second.

 Monostable – changes state only once per trigger

         pulse – also called a ONE-SHOT or It is called a TIMER or DELAY.

 Voltage Controlled Oscillator – called a VCO.
