Line Card Access Switch
INTEGRATED CIRCUITS DIVISION
PRELIMINARY
Features
• Improved switch dV/dt immunity of 1500V/s
• Drop-In Replacement for CPC7595
• Replaces CPC7585, and allows removal of
power-up control discrete components
• Enhanced SW8, Ringing Test Switch, breakdown
voltage
• TTL logic level inputs for 3.3V logic interfaces
• Smart logic for power-up / hot-plug state control
• Small 20-pin or 28-pin SOIC Package
• Monolithic IC reliability
• Low, matched, RON
• Eliminates the need for zero-cross switching
• Flexible switch timing for transition from Ringing
mode toTalk mode.
• Clean, bounce-free switching
• SLIC tertiary protection via integrated current
limiting, voltage clamping, and thermal shutdown
• 5V operation with power consumption <10.5 mW
• Intelligent battery monitor
Applications
• Standard voice linecards
• Integrated Voice and Data (IVD) linecards
• Central office (CO)
• Digital Loop Carrier (DLC)

Description
The CPC7695 is a member of IXYS Integrated
Circuits Division’s third-generation Line Card Access
Switch (LCAS) family. This monolithic 10-pole line
card access switch is available in a 20-pin or 28-pin
SOIC package. It provides the necessary functions to
replace three 2-Form-C electromechanical relays on
analog line cards or combined voice and data line
cards found in central office, access, and PBX
equipment. The device contains solid state switches
for tip and ring line break, ringing injection, and test
access. The CPC7695 requires only a +5V supply and
provides stable start-up conditioning during system
power-up and for hot-plug insertion. Once active, the
inputs respond to traditional TTL logic levels, enabling
the CPC7695 to be used with 3.3V-only logic.
