IL 817TE

Overview

The IL 817TE is a general-purpose digital isolator from the IsoLoop series, manufactured by NVE Corp/Isolation Products. It features four channels with a 2500Vrms isolation voltage and utilizes Giant Magnetoresistive (GMR) technology. The device supports data rates up to 110Mbps and offers a common-mode transient immunity of 100kV/µs. It operates within a supply voltage range of 3V to 5.5V and functions across an extended temperature range of -40°C to 125°C. The component is housed in a 16-SOIC surface-mount package.

Feature Summary

• Utilizes GMR technology for high-speed signal transmission
• Provides robust common-mode transient immunity
• Supports bidirectional or unidirectional channel configurations

Applications

• Industrial automation systems
• Medical equipment isolation
• Power electronics control circuits

Procurement Notes

Verify the specific suffix against official documentation to confirm pinout and functional variations. Ensure compatibility with existing board layouts regarding the 16-SOIC footprint. Confirm RoHS compliance status for regulatory adherence. Cross-reference datasheet revisions to validate parameter consistency before finalizing procurement decisions.

Selection Notes

Select this component when high CMTI and moderate speed are required in a compact surface-mount form factor. Compare performance metrics against capacitive isolators for noise immunity requirements. Evaluate thermal management needs given the operating temperature range. Consider channel count requirements to optimize board space usage effectively.

Part Context

This part belongs to the IsoLoop family, which leverages magnetic sensing for isolation. It shares architectural similarities with other IL series devices but differs in channel count and package type. The 16-SOIC variant provides a balance between density and ease of assembly compared to smaller packages.

Replacement Considerations

Direct substitutes include IL 717TE and IL 817E. Verify pin compatibility and electrical specifications before substitution.
