CPC7582
Line Card Access Switch
Features
• Small 16-pin SOIC and 16-pin DFN
• DFN package printed-circuit board footprint is 60
percent smaller than the SOIC version, 70 percent
smaller than 4th generation EMR solutions.
• Monolithic IC reliability
• Low matched RON
• Eliminates the need for zero cross switching
• Flexible switch timing to transition from ringing mode
to talk mode.
• Clean, bounce-free switching
• Tertiary protection consisting of integrated current
limiting, voltage clamping, and thermal shutdown for
SLIC protection
• 5 V operation with power consumption < 10 mW
• Intelligent battery monitor
• Latched logic-level inputs, no external drive circuitry
required
• SOIC version is pin compatible with Agere product
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 SOIC or DFN surface-mount package. It
provides the necessary functions to replace two
2-Form-C electro-mechanical relays on traditional
analog and integrated voice and data (IVD) line cards
found in Central Office, Access, and PBX equipment.
The device contains solid state switches for tip and
ring line break, ringing injection/ringing return and 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.
The CPC7582xC logic states differ from the
CPC7582xA/B. See “Functional Description” on
page 12 for more information. The CPC7582xC also
has a higher trigger and hold current for the protection
SCR.
