ITC137P Datasheet Integrated Telecom Circuits

Manufacturer: IXYS (now Littelfuse)

Overview: INTEGRATED CIRCUITS DIVISION Parameter Relay Load Voltage Relay Load Current Relay On-Resistance (max) Bridge Rectifier Reverse Voltage Darlington Collector Current Darlington Current Gain Rating 350 120 15 100.

General Description

This Integrated Tele Circuit bines 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 ponent count in tele applications.

The ITC137’s optocoupler provides for full-wave detection of ringing signals.
