Single Bipolar Timer The NE555 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 wave forms, and the output structure can source or sink up to 200 MA.It is used in various moduler such as Led chaser and Water controller systems and any Other applience.. A pack of 10 No pcs IC NE555 with IC BASE of 8 Pins etc.
