CPC7695

Line Card Access Switch

Features

Description

• 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

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 used with 3.3V only logic.

• 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, R

• 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
