IL 611-3E

Overview

The IL 611-3E is a general-purpose digital isolator manufactured by NVE Corp/Isolation Products. It features two channels with a unidirectional input configuration (2 inputs, 0 outputs on the secondary side). The device utilizes Giant Magnetoresistance (GMR) technology and provides an isolation voltage of 2500Vrms. It supports data rates up to 100Mbps with a common-mode transient immunity of 15kV/µs. Operating temperatures range from -40°C to 85°C, and it functions within a supply voltage range of 3V to 5.5V. The component is available in an 8-SOIC package.

Feature Summary

• Utilizes Giant Magnetoresistance (GMR) technology for signal transmission

Procurement Notes

Verify the specific suffix against official documentation to confirm pinout and electrical characteristics. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the supplier source matches the manufacturer's authorized distribution network to guarantee part authenticity and traceability.

Selection Notes

Select this component when GMR-based isolation is required for low electromagnetic interference applications. Consider the 100Mbps data rate capability for high-speed serial communications. Verify that the 8-SOIC package dimensions fit the target PCB layout constraints and that the operating temperature range meets environmental specifications.

Part Context
