NE558

www.fairchildsemi.com NE558 Quad Timer Features Wide Supply Voltage Range: 4.5V To 16V 100 mA Output Current Per Section Edge Triggered Without Coupling Capacitor Time Period Equals RC Output independent Of Trigger Conditions Description The NE558 series are monolithic Quad Timers which can be used to produce four entirely independent timing functions. These highly stable, general purpose controllers can be used in a monostable mode to produce accurate time delays, from microseconds to hours. The time is precisely controlled by one external resistor and one capacitor in the time delay mode. A stable mode can be operated using two of four time sections.
