IL 711-1E

Overview

The IL711-1E is a two-channel digital isolator from the IsoLoop family, utilizing Giant Magnetoresistive (GMR) technology. It supports data rates up to 110 Mbps with a maximum propagation delay of 15 ns and typical rise/fall times of 1 ns. The device operates on a supply voltage range of 3 V to 5.5 V and provides 1000 Vrms isolation voltage. It features a minimum Common Mode Transient Immunity (CMTI) of 100 kV/µs and functions within an industrial temperature range of -40°C to 100°C.

Feature Summary

• Employs GMR sensor technology for high-speed signal transmission without magnetic field interference
• Provides robust galvanic isolation with high common-mode transient immunity
• Ensures low power consumption through minimal input current requirements

Applications

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

Procurement Notes

Verify the specific suffix against official NVE documentation to confirm package type and isolation rating. Datasheets indicate variations exist; ensure the selected part matches the required 1000 Vrms or 2500 Vrms specification and physical footprint before ordering.

Selection Notes

Select this component for applications requiring high CMTI and low propagation delay in compact packages. Compare channel configurations and isolation voltages against other IL series variants to match circuit requirements precisely.
