IL 715-3B

Overview

The IL715-3B is a four-channel high-speed digital isolator manufactured by NVE. It utilizes patented IsoLoop spintronic technology to provide galvanic isolation between circuits operating at different voltage levels. The device features a data rate of 110 Mbps and offers common-mode transient immunity of 100 kV/µs. It operates with a maximum supply voltage of 5.5 V and provides an isolation voltage rating of 2.5 kVrms. The component is housed in a 16-pin SOIC package.

Feature Summary

• Patented IsoLoop spintronic technology for robust signal transmission
• High common-mode transient immunity for noise rejection
• No carrier or clock signals required for operation
• Low electromagnetic interference emissions

Applications

• Galvanic isolation between microcontrollers and peripheral devices
• Isolation in industrial communication buses
• Signal isolation in power monitoring systems
• Noise reduction in mixed-signal environments

Procurement Notes

Verify the specific suffix (e.g., -3B vs -3E) against official NVE documentation, as it may indicate variations in packaging or temperature range. Confirm RoHS compliance status directly from the manufacturer's datasheet. Ensure the supplier provides traceable documentation matching the exact part number to avoid counterfeit components.

Selection Notes

Select this component when high-speed digital isolation is required without the need for external oscillators. The four-channel configuration supports parallel data lines efficiently. Consider the 16-pin SOIC package constraints for PCB layout. Verify that the 2.5 kVrms isolation rating meets the safety requirements of the target application environment.

Part Context

The IL715 series belongs to NVE's family of high-speed digital isolators. These devices are designed to replace traditional optocouplers in applications demanding higher speed and lower power consumption. The series includes variants with different channel counts and pin configurations to suit diverse interface needs.

Replacement Considerations

The IL715-3E is a documented variant within the same product family. Verify if the suffix difference implies changes in packaging or operational parameters before substitution.
