Product specification
NE558
DESCRIPTION
The 558 Quad Timers are monolithic timing devices which can be
used to produce four independent timing functions. The 558 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 558 are edge-triggered; therefore,
when connected in tandem for sequential timing applications, no
coupling capacitors are required. Output current capability of 100mA
is provided in both devices.
FEATURES
• 100mA output current per section
• Edge-triggered (no coupling capacitor)
• Output independent of trigger conditions
• Wide supply voltage range 4.5V to 16V
• 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
