IL4622E

Overview

The IL4622E is a high-speed, fully-isolated RS-422/RS-485 transceiver manufactured by NVE Corp. It features integrated DC-to-DC converters for galvanic isolation and supports full-duplex connections for RS-422 buses. The device operates within a supply voltage range of 3V to 3.6V or 3V to 5.5V and functions across a temperature range of -40°C to 85°C (TA). It is housed in a 16-SOIC package with a width of 7.50mm.

Feature Summary

• Integrates DC-to-DC converter for complete galvanic isolation
• Supports full-duplex communication on RS-422 buses
• Utilizes NVE's proven magnetic isolation technology

Applications

• Industrial automation control systems
• High-noise environment data transmission
• Isolated serial communication interfaces

Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to ensure correct package and temperature grade. Confirm that the integrated DC-DC converter requirements align with system power architecture. Check isolation voltage ratings against application safety standards before procurement.

Selection Notes

Select this component when full-duplex RS-422 communication is required with high-level galvanic isolation. The integrated power converter simplifies design by eliminating external isolation barriers. Ensure the 16-SOIC footprint fits the PCB layout constraints.

Part Context

This part belongs to the IL4xxx series of high-speed isolated transceivers from NVE Corporation. It is distinct from half-duplex variants like the IL4685E, specifically designed for full-duplex RS-422 applications while maintaining robust electromagnetic interference immunity through magnetic coupling.

Replacement Considerations

Direct substitutes include other parts within the IL4xxx series such as the IL4685E for half-duplex needs, provided the interface protocol matches. Verify pin compatibility and isolation specifications when considering alternative manufacturers.
