NE558
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
Timer intervals from microseconds to hours
Time period equals RC
Military qualifications pending.
APPLICATIONS
Sequential timing
Time delay generation
Precision timing
Industrial controls
Quad one-shot.
