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.
