CPC7591BA集成電路（IC）的電信規(guī)格書(shū)PDF中文資料

Description

The CPC7591 is a member of IXYS Integrated Circuits Division’s next generation Line Card Access Switch (LCAS) family. This monolithic 4-pole solid state switch is available in a 16-pin SOIC package. It provides the necessary functions to replace the 2-Form-C electromechanical ringing relay and it’s associated snubber circuitry on traditional analog line cards or contemporary integrated voice and data (IVD) line cards found in Central Office (CO), Access, and PBX equipment. Because this device contains solid state switches for tip and ring line break and for ringing injection/return, it requires only a +5 V supply for operation and TTL logic-level inputs for control. The CPC7591 provides stable start-up conditioning during system power up and for hot plug insertion applications. Once active, the inputs respond to traditional TTL logic levels, enabling the CPC7591 to be used with 3.3V-only logic.
