Ordering Information
Pin Configuration
The Integrated Telecom Circuit combines a single-pole,
normally open (1-Form-A) solid state relay, a bridge
rectifier, a Darlington transistor, and an optocoupler
into one 16-pin SOIC package, consolidating designs
and reducing component count in telecom applications.
The ITC117PL's relay features the added benefit of
current limiting, and the optocoupler provides for full-
wave detection of ring signals.
