IL 712-2

Overview

The IL712-2 is a dual-channel digital isolator from NVE Corp/Isolation Products, utilizing IsoLoop® GMR technology. It provides 2500Vrms isolation with a data rate of 110Mbps and 100kV/µs CMTI. Operating on 3V to 5.5V supplies, it features 15ns max propagation delay and 3ns max pulse width distortion. The device supports -40°C to 125°C operation in an 8-pin PDIP package.

Feature Summary

• Utilizes patented IsoLoop spintronic Giant Magnetoresistive (GMR) technology for galvanic isolation without optical components.
• Provides high-speed signal transmission with low propagation delay and minimal pulse width distortion.
• Offers robust common-mode transient immunity suitable for noisy industrial environments.
• Compatible with standard +5V and +3.3V CMOS logic levels.

Applications

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

Procurement Notes

Verify the specific suffix '2' indicates the 8-pin PDIP package variant when ordering. Confirm that the required operating temperature range extends to 125°C, as some variants may be limited to 100°C. Ensure compatibility with the target PCB footprint for the DIP-8 form factor before finalizing procurement.

Selection Notes

Select this component for applications requiring high-speed isolation with superior transient immunity compared to traditional optocouplers. The GMR technology offers longer barrier life and consistent performance over time. Consider the 8-pin PDIP package if through-hole mounting is required for mechanical stability or prototyping needs.

Part Context

The IL712-2 belongs to the IsoLoop family of digital isolators, which leverage giant magnetoresistive sensors for signal transfer. This series replaces older optocoupler technologies by eliminating light-emitting diodes, thereby improving reliability and speed. The IL712 specifically denotes the dual-channel configuration within this architecture.

Replacement Considerations

Direct substitutes include the IL711-2 for single-channel requirements or the IL712S for surface-mount SOIC packaging. Verify pinout compatibility and voltage isolation ratings when cross-referencing with other GMR isolators or high-speed digital isolators from different manufacturers.
