IL 711S-3E

Overview

The IL711S-3E is a general-purpose digital isolator from NVE's IsoLoop series, utilizing Giant Magnetoresistance (GMR) technology. It features two channels with a maximum data rate of 150 Mbps and a common-mode transient immunity of 100 kV/µs. The device operates on a single supply voltage between 3 V and 5.5 V and provides 2500 Vrms isolation. Key timing parameters include a maximum propagation delay of 15 ns and typical rise/fall times of 1 ns. It is housed in an 8-SOIC package and supports an operating temperature range of -40°C to 100°C.

Feature Summary

• Utilizes GMR technology for high-speed signal transmission
• Provides robust 2500 Vrms electrical isolation barrier
• Features high common-mode transient immunity of 100 kV/µs

Applications

• General purpose digital isolation
• Industrial communication interfaces
• Power electronics control circuits

Procurement Notes

Verify the specific suffix 'S-3E' against official NVE documentation to confirm pinout and functional specifications. Ensure compatibility with system voltage requirements within the 3 V to 5.5 V range. Confirm that the 8-SOIC package dimensions align with PCB layout constraints. Check for RoHS compliance status if required by regulatory standards.

Selection Notes

Select this component when high-speed isolation up to 150 Mbps is required alongside strong noise immunity. The GMR technology offers advantages over optical or capacitive alternatives in terms of stability. Consider the 8-SOIC footprint for space-constrained designs. Verify that the 2500 Vrms rating meets the safety isolation requirements of the target application environment.

Part Context

This part belongs to the IL711 family of digital isolators from NVE Corporation. It is part of the IsoLoop product line, which leverages proprietary GMR sensor technology. The family includes variants with different channel counts and speeds, such as the IL712 for dual-channel applications. These devices are designed for reliable performance in harsh electromagnetic environments.

Replacement Considerations

Direct substitutes may include other IL711 variants with compatible suffixes. Cross-referencing with IL712 models is possible if channel count differences are acceptable. Verify pin-to-pin compatibility before substitution. Consult NVE datasheets for detailed parameter comparisons.
