IL 711-2

Overview

The IL 711-2 is a general-purpose digital isolator from the IsoLoop series, manufactured by NVE Corp/Isolation Products. It utilizes Giant Magnetoresistive (GMR) technology to provide galvanic isolation without an integrated power supply. The device features two unidirectional channels with a data rate of 110Mbps and a common-mode transient immunity of 100kV/µs. It operates within a voltage range of 3V to 5.5V and supports propagation delays of up to 15ns. The component is housed in an 8-DIP package suitable for through-hole mounting.

Feature Summary

• Utilizes GMR technology for high-speed signal transmission
• Provides robust galvanic isolation between circuits
• Supports standard CMOS logic levels

Applications

• Isolated data transmission systems
• Fieldbus isolation interfaces
• High-speed digital system interconnects

Procurement Notes

Verify the specific suffix against the datasheet to confirm package type and temperature rating. Ensure the ordering code matches the required isolation voltage and channel configuration. Confirm RoHS compliance status for regulatory adherence. Check for any recent packaging or labeling changes documented in product change notices before finalizing procurement orders.

Selection Notes

Select this component when high-speed bidirectional communication is not required, as it supports only unidirectional channels. Consider the 8-DIP package constraints for PCB layout and thermal management. Evaluate the 2500Vrms isolation barrier against system safety requirements. Compare input current specifications with driving source capabilities to ensure proper logic level shifting performance.

Part Context

This part belongs to the IsoLoop family of magnetic digital isolators. It shares core architectural similarities with other IL71x series devices but differs in pinout and package options. The technology relies on magnetic coupling rather than optical or capacitive methods, offering distinct reliability characteristics compared to alternative isolation technologies in the market.

Replacement Considerations

Cross-reference tools may suggest parametrically similar parts, but functional equivalence must be verified. Ensure substitute components match the unidirectional channel count and GMR-based isolation mechanism if specific magnetic properties are required.
