SINGLE TIMER
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.
*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.
