ISL6413IR-TK

Overview

The ISL6413IR-TK is a dual-channel, high-speed line driver and receiver designed for RS-422/RS-485 communication applications. It integrates two independent drivers and receivers on a single chip, supporting data rates up to 10 Mbps. The device features fail-safe circuitry to ensure a high logic state at the receiver output when inputs are open or disconnected. It operates from a single 3.3V supply and includes thermal shutdown protection. The component is housed in an 8-pin SOIC package, suitable for surface-mount assembly in industrial and commercial environments requiring robust differential signaling.

Feature Summary

• Supports RS-422 and RS-485 differential communication standards
• Integrated fail-safe mechanism maintains high receiver output during input disconnect
• Thermal shutdown protection prevents damage under excessive power dissipation

Applications

• Industrial automation control systems
• Building automation networks
• Data acquisition systems

Procurement Notes

Verify the specific suffix 'TK' against the manufacturer's official documentation to confirm tape-and-reel packaging specifications and exact temperature grade. Ensure compatibility with standard 8-pin SOIC footprint dimensions during PCB layout review. Confirm RoHS compliance status through current datasheet revisions before finalizing procurement orders.

Selection Notes

Select this component for designs requiring dual-channel differential transmission with integrated fault protection. Consider the 10 Mbps speed limit and 3.3V operating voltage when matching system requirements. Evaluate the SOIC package size constraints relative to available board space and thermal management capabilities in the target enclosure environment.

Part Context

This part belongs to the Intersil (now Renesas) family of high-speed transceivers. It serves as a compact solution for replacing discrete driver/receiver combinations in legacy RS-485 networks. The integration reduces component count and simplifies design complexity compared to older multi-chip approaches for similar communication interfaces.

Replacement Considerations

Check for direct pin-compatible alternatives such as the MAX3485E or SN75176 series, ensuring voltage levels and data rate specifications match the original design requirements. Verify that any substitute maintains the same fail-safe behavior and thermal protection characteristics.
