• NE558 QUAD TIMER


DESCRIPTION


The NE558 Quad Timers are monolithic timing devices which can be


used to produce four independent timing functions. The NE558


output sinks current. These highly stable, general purpose


controllers can be used in a monostable mode to produce accurate


time delays—from microseconds to hours. In the time delay mode of


operation, the time is precisely controlled by one external resistor


and one capacitor. A stable operation can be achieved by using two


of the four timer sections.


The four timer sections in the NE558 are edge-triggered; therefore,


when connected in tandem for sequential timing applications, no


coupling capacitors are required. Output current capability of


100 mA is provided in both devices.


FEATURES


100 mA output current per section


Edge-triggered (no coupling capacitor)


Output independent of trigger conditions


Wide supply voltage range 4.5 V to 16 V
