Description
The CPC7594 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 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
• Monolithic IC Reliability
• Low Matched RON
• Eliminates the Need for Zero-Cross Switching
