CPC7581  
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 RDSON  
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
