IL 611-2E

Overview

The IL611-2E is a general-purpose digital isolator manufactured by NVE Corp. It features two independent channels providing 2500Vrms isolation voltage with a common-mode transient immunity of 15kV/µs. The device supports data rates up to 100Mbps and operates within a supply voltage range of 3.0V to 5.5V. Packaged in an 8-DIP (0.300 inch width) format, it utilizes Giant Magnetoresistance (GMR) technology for signal transmission across the isolation barrier.

Feature Summary

• Utilizes Giant Magnetoresistance (GMR) technology for internal signal DC processing
• Provides high common-mode transient immunity of 15kV/µs
• Supports bidirectional data transmission across the isolation barrier

Applications

• General purpose digital isolation in industrial control systems
• Isolation interfaces for microcontroller-based applications
• Signal isolation in power monitoring equipment

Procurement Notes

Verify the package type matches the required 8-DIP configuration when sourcing. Confirm that the specific suffix '2E' corresponds to the dual-channel variant rather than single or quad-channel alternatives. Ensure compatibility with standard DIP footprint requirements for PCB layout integration.

Selection Notes

Select this component for applications requiring robust isolation between low-voltage logic and higher voltage domains. The 100Mbps speed rating suits moderate-speed communication protocols. Consider the 8-DIP package constraints regarding board space and pin count relative to system interface requirements.

Part Context

This part belongs to NVE's IL series of digital isolators, which leverage proprietary GMR semiconductor materials. These devices offer lower electromagnetic interference compared to traditional capacitive isolation technologies. The series includes variants with different channel counts and package options to suit diverse design needs.

Replacement Considerations

The ADUM3201 is identified as a base part number equivalent. Verify pinout compatibility and electrical specifications before substitution. Check if alternative packages like SOIC are acceptable for the target application.
