IL4822E

Overview

The IL4822E is a digital isolator manufactured by NVE Corp/Isolation Products, utilizing Giant Magnetoresistive (GMR) technology. It features four channels with a maximum data rate of 110 Mbps and an isolation voltage of 2500 Vrms. The device operates within a supply voltage range of 3V to 5.5V and supports a wide operating temperature range from -40°C to 125°C. Packaged in a 16-pin SOIC format, it provides high common-mode transient immunity of 100 kV/µs. Key electrical parameters include a propagation delay of 18 ns, rise time of 4 ns, and low input current of 10 µA.

Feature Summary

• Utilizes GMR technology for robust signal transmission across isolation barriers
• Provides high common-mode transient immunity to resist noise interference
• Supports bidirectional or unidirectional data flow depending on channel configuration

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing safety-certified signal isolation
• Power electronics control circuits

Procurement Notes

Verify the specific suffix 'E' against official documentation to confirm package type and temperature rating. Ensure compatibility with system voltage levels and isolation requirements before procurement. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when high-speed digital isolation is required in noisy environments. Consider the 16-SOIC package constraints and thermal management needs for high-temperature applications. Verify that the 2500 Vrms isolation rating meets the safety standards of the target application.

Part Context

The IL4822E belongs to the IsoLoop family of digital isolators from NVE. These devices leverage proprietary GMR sensor technology to achieve reliable isolation without optical components. This series is designed for applications demanding high reliability and long-term stability in harsh industrial conditions.

Replacement Considerations

Check for direct substitutes such as the IL717E which shares similar channel counts and isolation ratings. Verify pinout compatibility and electrical specifications before substituting any alternative components.
