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.
