CPC7695

Line Card Access Switch

INTEGRATED

IRCUITS

IVISION

Features

Description

• Improved switch dV/dt immunity of 1500V/s

• Drop-In Replacement for CPC7595

• Replaces CPC7585, and allows removal of

power-up control discrete components

• Enhanced Ringing Test Switch, SW8, breakdown

voltage

The CPC7695 is a member of IXYS Integrated

Circuits Division’s third-generation Line Card Access

Switch (LCAS) family. This monolithic 10-pole line

card access switch is available in a 20-pin 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

• 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

equipment. The device contains solid state switches

for tip and ring line break, ringing injection, and test

access. The CPC7695 requires only a +5V 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.

• Low, matched, R

• Eliminates the need for zero-cross switching

• Flexible switch timing for transition from Ringing

mode toTalk mode.

• Clean, bounce-free switching

• SLIC tertiary protection via integrated current

limiting, voltage clamping, and thermal shutdown

• 5V operation with power consumption <10.5 mW

• Intelligent battery monitor
