CPC7691BA Datasheet | IXYS

Features - Improved switch d V/dt immunity of 1500V/s - Drop-In Replacement for CPC7591 - Replaces CPC7581, and allows removal of power-up control discrete ponents - TTL logic level inputs for 3.3V logic interfaces - Smart logic for power-up / hot-plug state control - Small 16-pin SOIC package - Monolithic IC reliability - Low, matched RON - Eliminates the need for zero-cross switching - Flexible switch timing for transition from ringing mode to idle/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 < 10.5 m W - Intelligent battery monitor - Latched logic-level inputs, no external drive circuitry Applications - Vo IP 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 Pb e3 Description The CPC7691 is a member of IXYS Integrated Circuits Division’s third-generation Line Card Access Switch (LCAS) family. This monolithic 4-pole solid state switch, available in a 16-pin SOIC package, 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 +5V supply for operation and TTL logic-level inputs for control. The CPC7691 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 CPC7691 to be used with 3.3V-only logic. For negative transient voltage protection the CPC7691BA version employs SCRs to provide voltage...
