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.
