MC1455DR2G Description
The MC1455DR2G monolithic timing circuit is a highly stable controller capable of producing accurate time delays or oscillations. Additional terminals are provided for triggering or resetting if desired. Time is precisely controlled by one external resistor and capacitor in the time delay mode. For astable operation as an oscillator, the free−running frequency and the duty cycle are accurately controlled with two external resistors and one capacitor. The circuit may be triggered and reset on falling waveforms, and the output structure can source or sink up to 200 mA or drive TTL circuits.
