IL 422

Overview

The IL422 is a galvanically isolated, high-speed differential bus transceiver designed for bidirectional data communication on balanced transmission lines. It integrates RS-422 and RS-485 interface capabilities within a single package. The device provides robust signal isolation with a rated voltage of 2500Vrms. It supports data rates up to 25Mbps and features a common-mode transient immunity (CMTI) of 20kV/µs. The component is housed in a 16-SOIC package.

Feature Summary

• Galvanic isolation for safe bidirectional data communication
• Integrated RS-422 and RS-485 transceiver functionality
• High common-mode transient immunity for noise rejection

Applications

• Industrial automation control systems
• Factory floor instrumentation networks
• Building automation interfaces

Procurement Notes

Verify the specific suffix (e.g., -3V, E) against the required supply voltage and package variant. Confirm that the 2500Vrms isolation rating meets system safety standards. Ensure the 16-SOIC footprint matches the PCB design. Cross-reference part numbers carefully as NVE Corp products may have distinct suffixes indicating temperature range or packaging options.

Selection Notes

Select this component when both RS-422 and RS-485 compatibility is required in a single channel. Consider the 25Mbps speed limit for network timing requirements. Evaluate the 20kV/µs CMTI for environments with significant electrical noise. Verify the 16-SOIC package dimensions for space constraints.

Part Context

NVE Corp produces magnetic isolation technology components. The IL series focuses on digital isolators combining interface protocols with isolation barriers. This product line targets industrial applications requiring reliable data transfer across potential ground differences.

Replacement Considerations

Consult official cross-reference tools for parametrically similar parts. Verify that substitutes match the 2500Vrms isolation rating and 16-SOIC package. Ensure compatible data rates and CMTI specifications are maintained.
