Features
Description
• TTL logic level inputs for 3.3V logic interfaces
• Smart logic for power up / hot plug state control
• Monolithic IC reliability
The CPC7592 is a member of IXYS Integrated
Circuits Division’s next generation Line Card Access
Switch family. This monolithic 6-pole solid-state switch
is available in a 16-pin SOIC package. It provides the
necessary functions to replace two 2-Form-C
• Low matched R

• Eliminates the need for zero cross switching
• Flexible switch timing to transition from ringing mode
to talk mode.
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
• Clean, bounce-free switching
• Tertiary protection consisting of integrated current
limiting, voltage clamping, and thermal shutdown for
SLIC protection
• 5V operation with power consumption < 10 mW
• Intelligent battery monitor
• Latched logic-level inputs, no external drive circuitry
required
• Small 16-pin SOIC Package
injection/return, and test access, it needs only a +5V
supply for operation and logic-level inputs for control.
The CPC7592 is very similar to the CPC7582 with the
addition of controlled start-up states and TTL
compatible logic inputs.
The CPC7592BC logic provides alternative test states
from the CPC7592BA/BB while also providing greater
protection SCR trigger and hold current ratings.
Applications
• VoIP Gateways
• Central office (CO)
• Digital Loop Carrier (DLC)
• PBX Systems
Ordering Information
• Digitally Added Main Line (DAML)
• Hybrid Fiber Coax (HFC)
• Fiber in the Loop (FITL)
• Pair Gain System
