IL 611-1

Overview

The IL 611-1 is a general-purpose digital isolator manufactured by NVE Corp/Isolation Products. It features two independent channels with a unidirectional signal path, providing electrical isolation of 2500Vrms. The device utilizes Giant Magnetoresistive (GMR) sensing technology and operates on a single supply voltage ranging from 3V to 5.5V. It supports data rates up to 40Mbps and offers a common-mode transient immunity of 15kV/µs. The component is available in an 8-TSSOP or 8-MSOP package with a width of 0.118 inches (3.00mm).

Feature Summary

• Utilizes GMR sensing technology for robust signal transmission across the isolation barrier.
• Provides high-speed data transfer capabilities supporting up to 40Mbps.
• Features high common-mode transient immunity to maintain signal integrity in noisy environments.

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment signal interfaces
• General-purpose digital communication isolation

Procurement Notes

Verify the specific suffix against official documentation to confirm package type and temperature range. Confirm RoHS compliance status and moisture sensitivity level prior to integration. Ensure the selected variant matches the required lead time and availability constraints for production planning.

Selection Notes

Select this component when high-speed isolation is required within a compact footprint. The GMR technology offers advantages over capacitive alternatives in certain noise environments. Verify that the 3V to 5.5V supply range aligns with the system power architecture and that the 8-pin package fits the PCB layout constraints.

Part Context

This part belongs to the IsoLoop series of digital isolators from NVE Corp/Isolation Products. The series leverages proprietary GMR sensor technology to provide reliable isolation without the need for internal isolated power supplies. It serves as a solution for breaking ground loops and protecting sensitive electronics in mixed-voltage systems.
