Description

The NE555 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.

Pin connections

(top view)

The circuit may be triggered and reset on falling

waveforms, and the output structure can source

or sink up to 200mA.
