NE555 Datasheet


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
esistors and one capacitor.

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