This Integrated Telecom Circuit combines a single-pole,
normally open (1-Form-A) solid state relay, a bridge
rectifier, a Darlington transistor, an optocoupler, and
three Zener diodes into one 16-pin SOIC package,
consolidating designs and reducing component count
in telecom applications.
The ITC137’s optocoupler provides for full-wave
detection of ringing signals.
