DESCRIPTION

   The NE555monolithictiming circuit isa highlystable controller capableofproducingaccuratetime delays or oscillation. In the time delay mode of operation, the time is precisely controlled by one external resistorandcapacitor.For astableoperationasanoscillator, the free running frequency and the duty cycle are both accurately controlled with two external resistors and one capacitor. 

◾ LOW TURN OFF TIME

◾ MAXIMUM OPERATING FREQUENCY

   GREATER THAN 500kHz

◾ TIMING FROM MICROSECONDS TO HOURS

◾ OPERATES IN BOTH ASTABLE AND

   MONOSTABLE MODES

◾ HIGH OUTPUT CURRENT CAN SOURCE OR

   SINK 200mA

◾ ADJUSTABLE DUTY CYCLE
