Description
The CPC7592 is a member of IXYS Integrated Circuits Division’s next generation Line Card Access Switch family. This monolithic 6-pole solid-state switch is available in a 16-pin SOIC 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 test access, it needs only a +5V supply for operation and logic-level inputs for control.
The CPC7592 is very similar to the CPC7582 with the addition of controlled start-up states and TTL compatible logic inputs.
The CPC7592BC logic provides alternative test states from the CPC7592BA/BB while also providing greater protection SCR trigger and hold current ratings.

Features
• TTL logic level inputs for 3.3V logic interfaces
• Smart logic for power up / hot plug state control
• 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
• 5V operation with power consumption < 10 mW
• Intelligent battery monitor
• Latched logic-level inputs, no external drive circuitry
   required
• Small 16-pin SOIC Package
