CPC7592
Line Card Access Switch
Features
• TTL logic level inputs for 3.3V logic interfaces
• Smart logic for power up / hot plug state control
• Small 16-pin SOIC or 16-Pin DFN Package
• DFN package printed-circuit board footprint is 60
percent smaller than the SOIC version, 70 percent
smaller than 4^th generation EMR solutions.
• Monolithic IC reliability
• Low matched R_ON
• 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
Applications
• VoIP Gateways
• 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 CPC7592 is a member of Clare’s next generation
Line Card Access Switch family. This monolithic 6-pole
solid-state switch is available in either a 16-pin SOIC
or a 16-pin DFN package. It provides the necessary
functions to replace two 2-Form-C electro-mechanical
relays used on traditional analog and contemporary
integrated voice and data (IVD) line cards found in
Central Office, Access, and PBX equipment. Because
this device contains solid state switches for tip and ring
line break, ringing injection/return and test access it
requires only a +5V supply for operation and
logic-level inputs for control.
The CPC7592 is very similar to the Clare CPC7582
with the addition of controlled start-up states and TTL
compatible logic inputs.
The CPC7592xC logic provides alternative test states
from the CPC7592xA/B and while also providing
greater protection SCR trigger and hold current
ratings.
