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.
