ne555 datasheet

ne555 datasheet


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.
