IL 3222E

Overview

The IL3222E is a dual-channel digital isolator from NVE Corp/Isolation Products, designed for RS-422 and RS-485 communication interfaces. It features a data rate of 110 Mbps and operates with a supply voltage range up to 5.5V. The device provides an isolation rating of 2.5 kVrms and supports operation at temperatures up to 125 °C. Packaged in a 16-SOIC format, it integrates magnetic coupling technology for signal transmission across isolation barriers.

Feature Summary

• Integrates dual-channel isolation for simultaneous bidirectional data transfer
• Supports standard RS-422 and RS-485 serial communication protocols
• Utilizes polymer/ceramic composite barrier for high reliability

Applications

• Industrial automation control systems
• Factory floor sensor networks
• HMI and display projects with external peripherals

Procurement Notes

Verify the specific suffix (e.g., -3E) against official datasheets to confirm package type and temperature grade. Ensure compatibility with existing RS-422/RS-485 transceiver designs. Confirm lead times as availability may vary by distributor. Check for RoHS compliance status if required for your region.

Selection Notes

Select this component when high-speed differential signaling isolation is required. Compare channel count and isolation voltage against system requirements. Consider the 16-SOIC footprint for PCB layout constraints. Evaluate thermal performance for high-temperature environments up to 125 °C.

Part Context

Part of the IsoLoop series, leveraging NVE's proprietary magnetic isolation technology. This series replaces traditional optical couplers in many industrial applications due to higher speed and longer lifespan. The IL3222E specifically targets robust serial communication needs in noisy electrical environments.

Replacement Considerations

Check for direct pin-compatible alternatives within the same family, such as the IL3222 without suffix variations, ensuring identical interface support and isolation ratings before substitution.
