Description
The CPC7582 is a monolithic solid state switch in a 16
pin surface mount SOIC package. It provides the nec-
essary functions to replace two 2-Form-C electro-
mechanical relays on analog line cards found in
Central Office, Access and PBX equipment. The
device contains solid state switches for tip and ring line
break, ring injection/ring return and line test access.
The CPC7582 requires only a +5V supply and offers
“break-before-make” or “make-before-break” switch
operation using simple logic level input control. There
are two versions of the CPC7582, the CPC7582BA
and the CPC7582BB. The “BA” version has a protec-
tion SCR which provides protection to the SLIC device
and subsequent 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
