IL 711-3

Overview

The NVE IL711-3E is a dual-channel digital isolator from the IsoLoop series, housed in an 8-pin SOIC package. It supports data rates up to 110 Mbps with a typical propagation delay of 10 ns and rise time of 4 ns. The device operates on supply voltages between 3 V and 5.5 V, drawing a maximum input current of 15 μA. It provides 2.5 kVrms isolation voltage and withstands a typical common-mode transient immunity of 30 kV/µs. Operating temperatures range from -40 °C to 125 °C.

Feature Summary

• Provides galvanic isolation for high-speed digital signal transmission
• CMOS compatible with +5V and +3.3V logic levels
• High common-mode transient immunity for noise rejection
• UL and IEC certified for safety compliance

Applications

• Isolated data transmission systems
• Fieldbus isolation interfaces
• High-speed digital system interconnects
• Logic level shifting between isolated domains

Procurement Notes

Verify the specific suffix (e.g., -3E) against the datasheet to confirm package type and temperature rating. Ensure the supplier documentation matches the manufacturer's official specifications for the IL711 series. Cross-reference pinouts and isolation ratings before integration.

Selection Notes

Select this component when high-speed isolation is required alongside low power consumption. The CMOS compatibility simplifies interface design with standard logic families. Verify that the operating voltage range aligns with the target system's supply rails and that the thermal performance meets the application's environmental constraints.

Part Context

The IL711-3 belongs to NVE's IsoLoop family, which utilizes proprietary magnetic isolation technology rather than optical or capacitive methods. This series offers true logic integration within an isolation product, distinguishing it from traditional optocouplers by providing higher speed and lower power consumption.

Replacement Considerations

Check for direct equivalents such as the IL711-2E for PDIP packaging variants. Verify functional compatibility with other NVE IsoLoop devices like the IL712 series if channel configuration differs.
