IL 485-3V

Overview

The IL 485-3V is a digital isolator from NVE Corporation, integrating an RS-422/RS-485 transceiver with galvanic isolation. It features three channels with two inputs on Side 1 and one input on Side 2. The device provides 2500Vrms voltage isolation and operates in a unidirectional configuration. It supports 3.3V and 5V logic levels and is housed in a 16-pin SOIC package.

Feature Summary

• Integrates RS-422/RS-485 transceiver functionality with digital isolation
• Provides high-voltage galvanic isolation for noise immunity
• Supports standard 3.3V and 5V logic interfaces
• Utilizes GMR technology for low electromagnetic interference

Applications

• Industrial automation communication systems
• Data acquisition equipment
• Medical electronic devices
• Human-machine interface (HMI) connections

Procurement Notes

Verify the specific datasheet version for the IL 485-3V to confirm pinout compatibility and electrical characteristics against your system requirements. Ensure that the 16-SOIC package dimensions match your PCB layout constraints. Confirm that the 2500Vrms isolation rating meets the safety standards required for your application's voltage domains.

Selection Notes

Select this component when a combined isolated transceiver and digital isolator is needed for RS-422 or RS-485 networks. It is suitable for designs requiring compact integration of signal conditioning and isolation. Consider the 16-pin SOIC footprint and the specific channel configuration (2 inputs on one side, 1 on the other) during schematic design.
