■ DESCRIPTION
The UTC NE555 is a highly stable timer integrated circuit. It can be operated in both Astable and Monostable mode. With monostable operation, the time delay is precisely controlled by one external and one capacitor. With a stable operation as an oscillator the frequency and duty cycle are both accurately controlled with two external resistors and one capacitor.

■ FEATURES
* High current driver capability (=200mA).
* Adjustable duty cycle.
* Timing from s to hours.
* Turn off time less than 2s.
* Operates in both astable and monostable modes.
