IL 711S-1E

Overview

The IL711S-1E is a high-speed digital isolator from NVE's IsoLoop family, featuring two independent channels in an 8-pin MSOP package. It supports data rates up to 150 Mbps with a typical propagation delay of 4 ns and pulse width distortion of 2 ns. The device operates on a single supply voltage between 3 V and 5.5 V, drawing a maximum input current of 10 µA. It provides 1000 Vrms isolation voltage and 100 kV/µs common-mode transient immunity. Operating temperatures range from -40°C to 100°C.

Feature Summary

• Utilizes GMR technology for high-speed signal transmission with minimal distortion
• Provides galvanic isolation with high common-mode transient immunity
• CMOS compatible logic levels for direct interface with standard digital circuits

Applications

• Isolated data transmission systems
• High-speed digital communication interfaces
• Logic level shifting applications

Procurement Notes

Verify the specific suffix 'S' indicates the 1000 Vrms isolation rating and 150 Mbps speed variant, distinct from the standard IL711 series. Confirm the '1E' designation corresponds to the 8-TSSOP/MSOP package configuration. Ensure compatibility with the required operating temperature range of -40°C to 100°C for the target environment.

Selection Notes

Select this component when high data throughput exceeding 100 Mbps is required alongside moderate isolation voltage. The low input current makes it suitable for power-sensitive designs. Compare against the IL711 for lower speed requirements or the IL717 for higher channel counts and isolation ratings.

Part Context

Part of the IsoLoop digital isolator family using Giant Magnetoresistance (GMR) technology. This series offers superior speed compared to traditional capacitive isolators while maintaining robust isolation barriers.

Replacement Considerations

IL711-1E: Lower speed (110 Mbps) and isolation (1000 Vrms). IL712S-1E: Dual-channel version of the same speed/isolation profile.
