Description
The Integrated Telecom Circuit combines a 1-Form-A solid
state relay, bridge rectifier, Darlington transistor, optocou-
pler and zener diodes into one 16 pin SOIC package, con-
solidating designs and reducing component count in
telecom applications. The ITC135P’s optocoupler provides
half wave ring detection.
