Description
The SC556 dual monolithic timing circuit is a highly stable controller capable of producing accurate time delays or
oscillation. In the time delay mode of operation, the time is precisely controlled by one external resistor and capacitor. For a
stable 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 waveforms, and the output structure can source or
sink up to 200mA.
