IL 711T-2E

Overview

The IL711T-2E is a general-purpose digital isolator from the IsoLoop series, manufactured by NVE Corp. It features two independent channels with unidirectional signal transmission and operates without an integrated isolated power supply. The device utilizes Giant Magnetoresistive (GMR) technology to provide galvanic isolation rated at 2500Vrms. It supports data rates up to 110Mbps with a common-mode transient immunity of 100kV/µs. Electrical parameters include a maximum propagation delay of 15ns and a typical rise/fall time of 1ns. It functions within a supply voltage range of 3V to 5.5V and is available in an 8-DIP package.

Feature Summary

• Utilizes GMR technology for high-speed digital isolation without magnetic saturation
• Provides robust common-mode transient immunity for noisy environments
• Operates on standard CMOS-compatible logic levels
• Supports bidirectional or unidirectional channel configurations

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 'T-2E' against the manufacturer's current datasheet to confirm the exact package variant and tape-and-reel status if applicable. Ensure the component meets RoHS3 compliance requirements for your target market. Cross-reference the UL and IEC certification numbers listed in the official documentation to validate safety ratings for end-use equipment.

Selection Notes

Select this component when high-speed data integrity is required alongside strong noise immunity. The GMR technology offers advantages over optical isolators regarding temperature stability and lifetime. Consider the 8-DIP package for through-hole assembly needs. Verify that the 2500Vrms isolation rating meets the safety standards of the application circuit.

Part Context

This part belongs to the IL711 family of digital isolators. The 'T' suffix typically denotes tube packaging, while '2E' indicates the dual-channel DIP configuration. It is part of NVE's IsoLoop product line, which distinguishes itself by using magnetic sensing rather than optical or capacitive coupling for signal transmission across the isolation barrier.

Replacement Considerations

Direct replacements include other variants within the IL711 family such as IL711-2E or IL711-3E, depending on the required package type (PDIP vs SOIC). Ensure any substitute maintains the same GMR technology characteristics and isolation voltage ratings.
