Description
The CPC7583 is a monolithic solid state switch in a 28 pin
surface mount SOIC package. It provides the necessary
functions to replace three 2-Form-C electromechanical re-
lays 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 re-
turn, line test access, test in access and ringing generator
testing. The CPC7583 requires only a +5V supply and of-
fers “break-before-make” or “make-before-break” switch
operation using simple logic level input control. The
CPC7583 has 4 versions. The CPC7583BA and the
CPC7583BC contain the integrated protection SCR while
the CPC7583BC and the CPC7583BD contain an extra
logic state which is detailed in later sections.
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
