Description
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.
Applications
Central office (CO)
Digital Loop Carrier (DLC)
PBX Systems
Digitally Added Main Line (DAML)
Hybrid Fiber Coax (HFC)
Fiber in the Loop (FITL)
Pair Gain System
Channel Banks
