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 i...
