IL 611-1E

Overview

The IL 611-1E is a general-purpose digital isolator from the IsoLoop series, manufactured by NVE Corp. It utilizes Giant Magnetoresistive (GMR) technology to provide electrical isolation without an isolated power supply. The device features two unidirectional channels with a 2500Vrms isolation voltage and a data rate of 10Mbps. It operates within a supply voltage range of 3V to 5.5V and supports a common-mode transient immunity of 15kV/µs. The component is housed in an 8-TSSOP or 8-MSOP package with a width of 3.00mm, suitable for surface mount applications across a temperature range of -40°C to 85°C.

Feature Summary

• Utilizes Giant Magnetoresistive (GMR) sensing technology for signal transmission
• Provides galvanic isolation between power domains without requiring isolated power supplies
• Features high common-mode transient immunity for reliable operation in noisy environments

Applications

• General-purpose digital signal isolation
• Isolation of microcontroller interfaces
• Industrial control system signal transmission

Procurement Notes

Verify the specific package variant, as the base model number may correspond to different suffixes indicating tape-and-reel or tube packaging. Confirm that the GMR-based architecture aligns with system requirements, as it differs from capacitive or optical isolation technologies. Ensure the 8-TSSOP footprint matches the PCB layout design before finalizing procurement orders.

Selection Notes

Select this component when a robust, magnetic-sensing based isolator is required for bidirectional or unidirectional digital signals. The IL 611-1E is appropriate for designs needing 2500Vrms isolation with low propagation delay. Consider the 8-pin TSSOP form factor for space-constrained applications where standard SOIC packages are too wide.
