IL 3285E

Overview

The IL3285E is a digital isolator from NVE Corp/Isolation Products, designed for RS422 and RS485 communication interfaces. It features a 16-SOIC package with a width of 0.295 inches (7.50mm). The device provides 2500Vrms isolation voltage and supports data rates up to 5Mbps. It exhibits a common-mode transient immunity (CMTI) of 15kV/µs. The component operates within a supply voltage range of 3V to 5.5V and functions reliably in temperatures from -40°C to 85°C.

Feature Summary

• Integrates GMR technology for robust signal transmission across isolation barriers
• Provides bidirectional data flow capability for serial communication protocols
• Ensures high noise immunity through significant common-mode transient rejection

Applications

• RS422 and RS485 bus interface isolation
• Industrial automation control systems
• Medical equipment signal isolation

Procurement Notes

Verify the specific suffix 'E' against official datasheets to confirm RoHS compliance status and exact pinout configuration. Ensure the selected package variant matches the required PCB footprint dimensions. Cross-reference the manufacturer's latest documentation to validate operating temperature ranges and electrical specifications before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring galvanic isolation for differential serial communication lines. It is suitable for applications needing moderate data speeds with reliable noise rejection. Consider the 16-SOIC package constraints and verify that the supply voltage requirements align with the system's power architecture.

Part Context

This part belongs to the IL3285 series of digital isolators manufactured by NVE Corp/Isolation Products. The series utilizes Giant Magnetoresistive (GMR) sensing technology to achieve isolation without optical components. These devices are engineered to replace traditional optocouplers in industrial and commercial applications requiring high reliability.

Replacement Considerations

Check for IL3285 variants with different suffixes or packages if pin compatibility or environmental ratings differ. Verify functional equivalence regarding data rate and isolation voltage before substituting.
