Line Card Access Switch

Features

Description

The CPC7595 is a member of Clare’s next generation

Line Card Access Switch (LCAS) family. This

• 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

• Improved switch dv/dt immunity of 500 V/μs

• Small 20 pin or 28 pin SOIC or 28 pin, thermally

enhanced dual, flat, no-lead (DFN) package

• DFN version provides 65% PCB area reduction over

monolithic 10-pole line card access switch is available

in a 20 or 28 pin SOIC or a 28 pin DFN 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 CPC7595

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 CPC7595 to

be used with 3.3V only logic.

4 generation EMRs

• 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

Ordering Information

For delivery in tubes, specify CPC7595Zx for the 20

pin SOIC (38/tube), CPC7595Bx for the 28 pin SOIC

(27/tube), or CPC7595Mx for the DFN (33/tube). For

tape and reel delivery, add “TR”, without quotes, to the

part number. SOIC: 20 or 28 pin (500/reel), DFN

(1000/reel).

Applications

• Standard voice linecards

• Integrated Voice and Data (IVD) linecards

• Central office (CO)

• Digital Loop Carrier (DLC)

• PBX Systems

• Digitally Added Main Line (DAML)

• Fiber in the Loop (FITL)

• Pair Gain System
