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 ITC137P’s optocoupler provides
for ful wave detection of the ring signal.
Features
• Small 16 Pin SOIC Package (PCMCIA Compatible)
• Board Space and Cost Savings
• 2mW Hookswitch Drive Power (Logic Compatible)
• No Moving Parts
• 3750VRMS Input/Output Isolation
• FCC Compatible Part 68
• Full-Wave Bridge Rectifier
• Darlington Transistor for Electronic Inductor “Dry”
Circuits
• Full Wave Current Detector for Ring Signal or Loop
Current Detect
• JEDEC Standard Pin Out
• Includes Zener Diodes
Approvals
• UL Recognized: File Number E76270
• CSA Certified: File Number LR 43639-12
