General Description

The NE555, SA555, and SE555 monolithic timing circuits are highly stable controllers 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.
