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)

Absolute Maximum Ratings are stress ratings. Stresses in
excess of these ratings can cause permanent damage to
the device. Functional operation of the device at these or
any other conditions beyond those indicated in the opera-
tional sections of this data sheet is not implied. Exposure of
the device to the absolute maximum ratings for an extend-
ed period may degrade the device and effect its reliability.
