Line Card Access Switch

Features

Description

• Small 16-pin SOIC or DFN package

The CPC7581 is a monolithic solid-state four-pole

switch in a 16-pin package. It provides the necessary

functions to replace a 2-Form-C electromechanical

relay on traditional analog and integrated voice and

data (IVD) line cards found in central office, access, and

PBX equipment. The CPC7581 contains solid-state

switches for tip and ring lead line break and ringing

injection/ringing return. The device requires only a +5 V

supply and offers break-before-make and

• DFN 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.

make-before-break operation using logic-level inputs.

• Clean, bounce-free switching

• Tertiary protection consisting of integrated current

limiting, 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

The CPC7581xA versions include an SCR that

provides protection to the SLIC and subsequent

circuitry during a fault condition. The CPC7581xC

versions are functionally identical to the CPC7581xA

versions, but with higher SCR hold current.

• SOIC package pin-compatible with Legerity product
