CPC7591

Line Card Access Switch

provides the necessary functions to replace the

2-Form-C electromechanical ringing relay and it’s

associated snubber circuitry on traditional analog line

cards or contemporary integrated voice and data (IVD)

line cards found in Central Office (CO), Access and

PBX equipment. Because this device contains solid

state switches for tip and ring line break and for ringing

injection/return it requires only a +5 V supply for

operation and logic-level inputs for control. The

CPC7591 provides stable start up conditioning during

system power up and for hot plug insertion

Features

• 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 16-pin SOIC or micro-leadframe package

• MLP package printed-circuit board footprint is 60

percent smaller than the SOIC version, 40 percent

smaller than fourth generation EMR solutions.

• Monolithic IC reliability

• Low, matched R

• Eliminates the need for zero-cross switching

• Flexible switch timing for transition from ringing

mode to idle/talk mode.

applications. Once active, the inputs respond to

traditional TTL logic levels enabling the CPC7591 to

be used with 3.3V only logic.

• 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

The CPC7591 is very similar to Clare’s CPC7581 with

the addition of defined start-up states and TTL

compatible logic inputs.

CPC7591xA and CPC7591xC versions include an

SCR that provides protection to the SLIC and

subsequent circuitry during a fault condition. The

CPC7591xC versions have a higher SCR hold current.

The CPC7591xB versions utilize clamping diodes to

• Latched logic-level inputs, no external drive circuitry

Applications

• VoIP Gateways

• Central office (CO)

• Digital Loop Carrier (DLC)

• PBX Systems

Ordering Information

Specify CPC7591Bx for the SOIC package (47/tube)

and CPC7591Mx for the MLP (94/tube). Add “TR”,

sans quotes, to the part number for tape and reel

packaging. SOIC: 1000/reel or MLP: 2000/reel.

• Digitally Added Main Line (DAML)

• Hybrid Fiber Coax (HFC)

• Fiber in the Loop (FITL)

• Pair Gain System

• Channel Banks
