Description

The KA558/KA558B series are monolithic Quad Timers

which can be used to produce four entirely independent tim-

ing functions. These highly stable, general purpose con-

trollers 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 oper-

ated using two of four time sections.
