The NE555 monolithic timing circuit is a highly stable
controller capableof producing accuratetime delays
or oscillation. In the time delay mode of operation,
the time is precisely controlled by one external re-
sistor and capacitor.For a stableoperation as an os-
cillator, the free running frequency and the duty cy-
cle are both accurately controlled with two external
resistors and one capacitor. The circuit may be trig-
gered and reset on falling waveforms, and the out-
put structure can source or sink up to 200mA. The
NE555 is available in plastic and ceramic minidip
package and in a 8-lead micropackage and in metal
can package version.
