IL 3222-3E

Overview

The IL3222-3E is a two-channel digital isolator utilizing Giant Magnetoresistive (GMR) technology. It supports RS422 and RS485 communication protocols with a data rate of 5 Mbps. The device provides 2500 Vrms isolation voltage and operates within a temperature range up to 125 °C. Packaged in a 16-pin SOIC format, it features unidirectional channel types for signal transmission across isolated boundaries.

Feature Summary

• Utilizes GMR technology for high-speed signal isolation
• Supports RS422 and RS485 protocol standards
• Provides robust electrical isolation between circuits

Applications

• Industrial communication systems requiring galvanic isolation
• RS485 bus networks in noisy environments
• Embedded control systems with ground potential differences

Procurement Notes

Verify the specific suffix '3E' against official NVE documentation to confirm package type and operating temperature range. Ensure compatibility with system voltage levels and isolation requirements before procurement. Cross-reference datasheet revisions for any updates on pinout or electrical characteristics.

Selection Notes

Select this component when RS422/RS485 isolation is required with moderate data rates. Consider the 16-pin SOIC package constraints and thermal performance limits. Evaluate the 5 Mbps speed against application needs compared to higher-speed alternatives in the NVE portfolio.
