CPC7695

Line Card Access Switch CPC7695 Features Improved switch dV/dt immunity of 1500 V/μs Drop-In Replacement for CPC7595 Replaces CPC7585, and allows removal of power-up control discrete components Enhanced SW8, Ringing Test Switch, breakdown voltage TTL logic level inputs for 3.3V logic interfaces Smart logic for power up / hot plug state control Small 20 pin or 28 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 talk mode. Clean, bounce-free switching SLIC tertiary protection via integrated current limiting, voltage clamping and thermal shutdown 5 V operation with power consumption < 10.5 mW Intelligent battery monitor Description The CPC7695 is a member of Clare’s third-generation Line Card Access Switch (LCAS) family. This monolithic 10-pole line card access switch is available in a 20- or 28-pin SOIC package. It provides the necessary functions to replace three 2-Form-C electromechanical relays on analog line cards or combined voice and data line cards found in central office, access, and PBX equipment. The device contains solid state switches for tip and ring line break, ringing injection and test access. The CPC7695 requires only a +5 V supply and provides stable start up conditioning during system power up and for hot plug insertion. Once active, the inputs respond to traditional TTL logic levels enabling the CPC7695 to be us...
