CPC7582
Line Card Access Switch
Features
• Small 16 pin surface mount SOIC package
• Monolithic IC reliability
• Low matched RDSON
• Eliminates the need for zero cross switching
• Flexible switch timing to transition from ringing mode
to idle/talk mode.
• Clean, bounce free switching
• Tertiary protection consisting of integrated current
limiting, thermal shutdown and SLIC protection
• 5V operation with power consumption <10mW
• Intelligent battery monitor
• Latched logic level inputs, no drive circuitry
• Pin to pin compatible to the Lucent 7582 family
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
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.
