Description

The 558 Quad Timers are monolithic timing devices which can be sed to produce four independent timing functions. The 558 output inks current. These highly stable, general purpose controllers can e used in a monostable mode to produce accurate time delays; rom microseconds to hours. In the time delay mode of operation, he time is precisely controlled by one external resistor and one apacitor. A stable operation can be achieved by using two of the our timer sections.
The four timer sections in the 558 are edge-triggered; therefore, hen connected in tandem for sequential timing pplications, no oupling capacitors are required. Output current capability of 100mA s provided in both devices.
