Features

Description

• Low, Matched R

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

• Eliminates the Need for Zero-Cross Switching

• 5V Operation With Power Consumption < 10 mW

• Flexible Switch Timing for Transition from Ringing

Mode to Idle/Talk Mode
