Description
The CPC7594 is a member of Clare’s next generation Line Card Access Switch family. This monolithic 6-pole solid-state switch is available in either a 16-pin SOIC or a 16-pin DFN package. It provides the necessary functions to replace two 2-Form-C electro-mechanical relays used on traditional analog and contemporary integrated voice and data (IVD) line cards found in Central Office, Access, and PBX equipment. Because this device contains solid state switches for tip and ring line break, ringing injection/return and channel test access, it requires only a +5V supply for operation and TTL logic-level inputs for control.

Features
• TTL logic level inputs for 3.3V logic interfaces
• Smart logic for power up / hot plug state control
• Small 16-pin SOIC or 16-pin DFN Package
• DFN package printed-circuit board footprint is 60 percent smaller than the SOIC version, 70 percent smaller than 4th generation EMR solutions.
• Monolithic IC reliability
• Low matched RON
• Eliminates the need for zero cross switching
• Flexible switch timing to transition from ringing mode to talk mode.
• Clean, bounce-free switching
• Tertiary protection consisting of integrated current limiting, voltage clamping, and thermal shutdown for SLIC protection
• 5 V operation with power consumption < 10 mW
• Intelligent battery monitor
• Latched logic-level inputs, no external drive circuitry required

Applications
• VoIP Gateways
• Central office (CO)
• Digital Loop Carrier (DLC)
• PBX Systems
• Digitally Added Main Line (DAML)
• Hybrid Fiber Coax (HFC)
• Fiber in the Loop (FITL)
• Pair Gain System
• Channel Banks
