DESCRIPTION
TheNE555monolithictimingcircuitisahighlystable
controllercapableofproducingaccuratetimedelays
or oscillation. In the time delay mode of operation,
the time is precisely controlled by one external re-
sistorandcapacitor.Forastableoperationasanos-
cillator, thefree runningfrequencyand theduty cy-
cle areboth accuratelycontrolled with twoexternal
resistors and one capacitor.The circuit maybe trig-
gered and reset on falling waveforms, andtheout-
put structurecan source or sink up to 200mA. The
NE555 is available in plastic and ceramic minidip
packageandin a8-leadmicropackageandinmetal
