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  
ON  
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
