www.fairchildsemi.com KA558/KA558B 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 KA558/KA558B 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.
