CPC7595

Line Card Access Switch

Features

Description

• Enhanced SW8, Ringing Test Switch, breakdown

The CPC7595 is a member of Clare’s next generation

voltage

Line Card Access Switch (LCAS) family. This

• TTL logic level inputs for 3.3V logic interfaces

monolithic 10-pole line card access switch is available

• Smart logic for power up / hot plug state control

in a 20 or 28 pin SOIC or a 28 pin DFN package. It

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

provides the necessary functions to replace three

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

2-Form-C electromechanical relays on analog line

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

cards or combined voice and data line cards found in

• DFN version provides 65% PCB area reduction over

central office, access, and PBX equipment. The

4th generation EMRs

device contains solid state switches for tip and ring line

• Monolithic IC reliability

break, ringing injection and test access. The CPC7595

• 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

Applications

• Standard voice linecards

• Integrated Voice and Data (IVD) linecards

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.

y Ordering Information

r For delivery in tubes, specify CPC7595Zx for the 20

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

a (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

in(1000/reel).
