NE555
SINGLE TIMER
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.
LINEAR INTEGRATED CIRCUIT
FEATURES
*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.
