IL 711S-1ETR7

Overview

The IL711S-1ETR7 is a two-channel digital isolator from NVE's IsoLoop series, utilizing Giant Magnetoresistance (GMR) technology. It provides bidirectional signal isolation with a typical data rate of 150 Mbps per channel and a common-mode transient immunity (CMTI) of 100 kV/µs. The device operates on a single supply voltage ranging from 3 V to 5.5 V and features tri-state outputs. It is housed in an 8-MSOP package and supports an operating temperature range of -40°C to 100°C.

Feature Summary

• Utilizes GMR technology for high-speed, low-power signal isolation without requiring isolated power supplies.
• Provides high common-mode transient immunity of 100 kV/µs to maintain signal integrity in noisy environments.
• Features tri-state outputs that allow multiple isolators to share bus lines effectively.

Applications

• High-speed CAN bus communication interfaces
• RS-485 and RS-422 serial communication links
• Industrial automation control systems

Procurement Notes

Verify the specific suffix 'TR7' indicates tape-and-reel packaging when ordering. Confirm the manufacturer is NVE Corp/Isolation Products to ensure authenticity. Check RoHS compliance status against current regulatory requirements. Validate the 8-MSOP package dimensions against your PCB footprint design. Ensure the datasheet version matches the production batch specifications.

Selection Notes

Select this component when high data rates up to 150 Mbps are required alongside robust noise immunity. The tri-state output capability makes it suitable for multi-drop bus architectures. Consider the 8-MSOP package size for space-constrained designs. Verify that the 3 V to 5.5 V supply range aligns with the system logic levels. Evaluate the CMTI rating against the expected noise environment of the application.

Part Context

This part belongs to the IL711S family within NVE's IsoLoop product line. It shares the core GMR isolation architecture with variants like the IL711S-1E but differs in packaging format. The S-series designation typically denotes optimized performance characteristics compared to standard versions. It complements other NVE isolators by offering a balance of speed and reliability.

Replacement Considerations

Direct substitutes include the IL711S-1E for tube packaging or the IL711S-1ETR13 for alternative reel quantities. Cross-reference pinouts and electrical parameters carefully before substitution. Ensure any replacement maintains the 150 Mbps data rate and 100 kV/µs CMTI ratings.
