Description:

The NTE955 series timing circuit is a highly stable controller capable of producing accurate time de lays, or oscillation. Additional terminals are provided for triggering or resetting if desired. In time delay mode of operation, the time is precisely controlled by one external resistor and capacitor. For astable operation as an oscillator, the free running frequency and the duty cycle are both accurately controlled with two external resistors and one capacitor. The circuit may be triggered and reset on falling wave forms, and the output structure can source or sink up to 200mA or drive TTL circuits.
