The 555 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.
This IC provides a highly accurate 555 Timer circuit that is capable of producing both time delays or oscillation. It is in a single 8 pin DIL package and can be operated in astable or monostable mode with external (RC) timing control. The 555 timer is a simple circuit. By taking the trigger signal from high to low the flip-flop is set. This causes the output to go high and the discharge pin to be released from GND (0V). The releasing of the discharge pin from GND causes an external capacitor to begin charging. When the capacitor is charged the voltage across it increases. This results in the voltage on the threshold pin increasing. When this is high enough it will result in the flip-flop to resetting. This causes the output to go low and the discharge pin is also taken back to GND. This discharges the external capacitor ready for the next time the device is triggered.
