IL 485E

Overview

The IL 485E is a digital isolator manufactured by NVE Corp/Isolation Products, utilizing Giant Magnetoresistance (GMR) technology. It provides galvanic isolation with a rating of 2500Vrms and supports data rates up to 110Mbps. The device features a common-mode transient immunity of 100kV/µs and operates within a supply voltage range of 3V to 5.5V. Designed for robust signal transmission in noisy environments, it offers low propagation delay and minimal electromagnetic interference.

Feature Summary

• Employs GMR technology for superior EMC performance and internal DC signal processing
• Provides high-speed data transmission capabilities suitable for demanding industrial applications
• Ensures reliable signal integrity through exceptional common-mode transient immunity

Applications

• Industrial communication systems requiring robust noise immunity
• Power electronics control circuits with high-voltage isolation needs
• Data acquisition systems operating in electrically noisy environments

Procurement Notes

Verify the specific package variant and suffix against official NVE documentation before ordering. Confirm that the selected component matches the required isolation voltage and data rate specifications for your application. Ensure compliance with RoHS standards and check for any recent product change notices affecting availability or pinout configuration.

Selection Notes

Select this component when high-speed digital isolation is required alongside extreme noise immunity. The GMR technology makes it suitable for applications where traditional capacitive isolators may suffer from EMI issues. Consider the operating temperature range and supply voltage requirements to ensure compatibility with the target system design constraints.

Part Context

This part belongs to the IsoLoop family of digital isolators from NVE Corp. These devices are designed to replace optocouplers in many applications, offering faster response times and better reliability. The IL series specifically targets general-purpose isolation needs with varying channel counts and speeds.

Replacement Considerations

Direct replacements may include other NVE IsoLoop variants such as the IL 485WE or IL 711T-2E depending on channel count and package requirements. Verify pinout compatibility and electrical parameters before substituting with components from other manufacturers.
