IL 611-2

Overview

The IL 611-2E is a general-purpose digital isolator from NVE Corp utilizing magnetic coupling technology. It features two independent channels with a data rate of 100 Mbps and common-mode transient immunity (CMTI) of 15 kV/µs. The device operates within a supply voltage range of 3 V to 5.5 V and supports an operating temperature range of -55°C to 125°C. It provides 2500 Vrms isolation voltage and is available in an 8-DIP package.

Feature Summary

• Utilizes magnetic coupling technology for deterministic galvanic isolation
• Provides high common-mode transient immunity of 15 kV/µs
• Supports dual-channel operation with 100 Mbps data rate

Applications

• Industrial automation systems requiring robust signal isolation
• Medical equipment needing reliable galvanic separation
• Power electronics control circuits

Procurement Notes

Verify the specific suffix, such as 'E' for enhanced specifications or packaging type, when ordering. Confirm that the required isolation voltage and channel count match the application needs. Ensure the operating temperature range meets environmental constraints. Cross-reference the package style, such as DIP or SOIC, with board layout requirements before finalizing procurement.

Selection Notes

Select this component when high-speed digital isolation is required alongside strong noise immunity. The magnetic coupling technology offers advantages over optical isolators regarding longevity and temperature stability. Consider the 100 Mbps data rate for applications demanding faster communication than standard isolators provide. Evaluate the 2500 Vrms isolation rating against system safety standards.

Part Context

This part belongs to the NVE IL 611 series of spintronic isolators. These devices leverage Giant Magnetoresistance (GMR) technology for signal transmission. The series includes variants with different channel counts and package options. The IL 611-2E specifically denotes the dual-channel version in a DIP package.

Replacement Considerations

Check for direct substitutes like the IL 611-3E for similar performance in a smaller SOIC package. Verify compatibility with existing circuit designs when switching between package types. Ensure replacement parts maintain the same isolation voltage and CMTI ratings.
