oscillation. In the time delay mode of operation, the time is precisely controlled by one external resistor and capacitor. For atPO嘉泰姆

stable operation as an oscillator, the free running frequency and the duty cycle are both accurately controlled with two externaltPO嘉泰姆

resistors and one capacitor. The circuit may be triggered and reset on falling waveforms, and the output structure can source ortPO嘉泰姆
