NE555 and NE556 applications AN170 1988 Dec 2 INTRODUCTION In mid 1972, Philips Semiconductors introduced the 555 timer , a unique functional building block that has enjoyed unprecedented popularity. The timer’s success can be attributed to several inherent characteristics foremost of which are versatility, stability and low cost. capacitance meter. The 555 integrated circuit tlruer is a monolithic timing circuit packaged either to the block diagram of Figure 1-7, providing the functions of control, trigger.

It works like a starter pistol to start the 555 timer running. The trigger is an active low trigger, which means that the timer starts when voltage on pin 2 drops to below 1/3 of the supply voltage. When the 555 is triggered via pin 2, the output on pin 3 goes high. 3: Output: Pin 3 is the output pin. 555 timer's output is digital in nature.

The 555 timer is an 8-pin IC that is capable of producing accurate time delays and/or oscillators. In the time delay mode, the delay is controlled by one external resistor and capacitor. In the oscillator mode, the frequency of oscillation and duty cycle are both controlled with two external resistors and one capacitor.
