Description
The NE558 series are monolithic Quad Timers which can
be used to produce four entirely independent timing func-
tions. 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 con-
trolled by one external resistor and one capacitor in the time
delay mode. A stable mode can be operated using two of
four time sections.
