Line Card Access Switch

Features

Description

• Small 16 pin surface mount SOIC package

The CPC7581 is a monolithic solid state switch in a 16 pin

surface mount SOIC package. It provides the necessary

functions to replace a 2-Form-C electromechanical relay

on analog line cards found in Central Office, Access and

PBX equipment. The device contains solid state switches

for tip and ring line break and ring injection/ring return.

The CPC7581 requires only a +5V supply and offers

“break-before-make” or “make-before-break” switch oper-

ation using simple logic level input control. There are two

versions of the CPC7581, the CPC7581BA and the

CPC7581BB. The “BA” version has a protection SCR

which provides protection to the SLIC device and subse-

quent circuitry during fault conditions.

• Monolithic IC reliability

• Low matched RDS_ON

• Eliminates the need for zero cross switching

• Flexible switch timing to transition from ringing mode

to idle/talk mode

• Clean, bounce free switching

• Tertiary Protection consisting of integrated current

limiting, thermal shutdown and SLIC protection

• 5V operation with power consumption <10mW

• Intelligent battery monitor

• Latched logic level inputs, no drive circuitry

• Pin to pin compatible to the Lucent 7581 family

Applications

• Central office (CO)

Ordering Information

• Digital Loop Carrier (DLC)

• PBX Systems

• Digitally Added Main Line (DAML)

• Hybrid Fiber Coax (HFC)

• Fiber in the Loop (FITL)
