ne555 datasheet
Description
These devices are monolithic timing circuits capable of producing accurate time delays or oscillation.
In the time delaymode of operation, the timed interval is controlled by a single external resistor and capacit
or network. In the astable mode of operation, the frequency andduty cy clemay beindependently
controlled with two external resistors and asingle external capacitor.
