CPC75282KA

Telecom Overview

The CPC75282KA is a Dual Line Card Access Switch (LCAS) from IXYS Integrated Circuits Division, housed in a 44-pin TQFP package. It provides the switching functionality of four Form-C relays within a single monolithic solid-state device. The IC operates on a +5V supply and supports battery voltages ranging from -19V to -72V. Key electrical parameters include an off-state leakage current of 1 µA at +25°C, an on-resistance matching tolerance of ±0.02Ω to 1.0Ω for break switches, and a transient immunity dV/dt rating of 1500 V/µs. The device features integrated tertiary protection including current limiting, voltage clamping, and thermal shutdown.

Telecom Feature Summary

• Monolithic solid-state construction providing low on-resistance and bounce-free switching without impulse noise generation.
• Integrated smart logic for power-up and hot-plug state control, eliminating the need for external driver circuitry.
• Flexible switch timing allowing transitions between ringing mode and talk mode with make-before-break or break-before-make options.
• Tertiary protection consisting of integrated current limiting, voltage clamping, and thermal shutdown for SLIC safety.

Telecom Applications

• VoIP Gateways
• Central Office (CO) analog line cards
• Digital Loop Carrier (DLC) systems
• PBX Systems
• Hybrid Fiber Coax (HFC) applications

Telecom Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging type. The CPC75282KA designation corresponds to the tube variant, while the KATR suffix indicates tape and reel packaging. Ensure compatibility with the required manufacturing process and moisture sensitivity levels before procurement.

Telecom Selection Notes

Select this component for applications requiring dual-channel telephone loop access switching. The device supports both break-before-make and make-before-break operations during ringing-to-talk transitions. Verify that the secondary protector selection ensures the voltage seen at tip and ring terminals remains below the switch breakdown voltage to meet ITU and IEC protection requirements.

Telecom Part Context

The CPC75282 belongs to IXYS Integrated Circuits Division’s next-generation Line Card Access Switch family. It replaces electromechanical relays in central office and PBX environments by offering a compact, economical solution for ringing and test access functions in analog line card designs.
