Features

• TTL logic level inputs for 3.3V logic interfaces

• Smart logic for power up / hot plug state control

• Small 16-pin SOIC or 16-pin DFN Package

• DFN package printed-circuit board footprint is 60

percent smaller than the SOIC version, 70 percent

smaller than 4th generation EMR solutions.

• Monolithic IC reliability

• Low matched R

ON

• Eliminates the need for zero cross switching

• Flexible switch timing to transition from ringing mode

to talk mode.

• Clean, bounce-free switching

• Tertiary protection consisting of integrated current

limiting, voltage clamping, and thermal shutdown for

SLIC protection

• 5 V operation with power consumption < 10 mW

• Intelligent battery monitor

• Latched logic-level inputs, no external drive circuitry

required

Applications

• VoIP Gateways

• Central office (CO)

• Digital Loop Carrier (DLC)

• PBX Systems

• Digitally Added Main Line (DAML)

• Hybrid Fiber Coax (HFC)

• Fiber in the Loop (FITL)

• Pair Gain System

• Channel Banks

Description

The CPC7594 is a member of Clare’s next generation

Line Card Access Switch family. This monolithic 6-pole

solid-state switch is available in either a 16-pin SOIC

or a 16-pin DFN package. It provides the necessary

functions to replace two 2-Form-C electro-mechanical

relays used on traditional analog and contemporary

integrated voice and data (IVD) line cards found in

Central Office, Access, and PBX equipment. Because

this device contains solid state switches for tip and ring

line break, ringing injection/return and channel test

access, it requires only a +5V supply for operation and

TTL logic-level inputs for control.

The CPC7594 is particularly designed for IVD line

cards where an EMR is required for line test due to the

high frequencies typical of ADSL but solid-state

switches are desired for switching and test-in

functions.

The CPC7594xC logic differs from the CPC7594xA/B

logic by providing a monitor function during the test

state.
