IL 717E

Overview

The IL717E is a general-purpose digital isolator from NVE Corp/Isolation Products, utilizing IsoLoop® technology based on Giant Magnetoresistance (GMR) sensing. It features four independent channels with a maximum data rate of 110 Mbps and a common-mode transient immunity of 100 kV/µs. The device operates within a supply voltage range of 3 V to 5.5 V and provides an isolation voltage of 2500 Vrms. It is housed in a 16-pin SOIC package with a width of 7.50 mm. The component supports a bidirectional signal configuration with three inputs on side 1 and one input on side 2, functioning without an isolated power supply.

Feature Summary

• Employs GMR-based IsoLoop technology for high-speed digital isolation without requiring isolated power supplies
• Provides robust signal integrity with 100 kV/µs common-mode transient immunity across four channels
• Supports bidirectional communication with asymmetric channel configurations for flexible system design

Applications

• Industrial automation control systems requiring galvanic isolation
• Medical equipment signal interfaces demanding high safety isolation standards
• Power electronics gate drive circuits for inverters and converters

Procurement Notes

Verify the specific suffix 'E' against official NVE documentation to confirm pinout and electrical characteristics match your schematic requirements. Ensure the 16-SOIC footprint dimensions align with your PCB layout constraints. Confirm that the 2500 Vrms isolation rating satisfies the safety regulations applicable to your target market and end-use environment.

Selection Notes

Select this component when high-speed data transmission up to 110 Mbps is required alongside strong noise immunity in environments with rapid voltage transients. The absence of an integrated isolated power supply reduces bill-of-materials complexity compared to transformer-based isolators. Consider the 16-pin SOIC package if space allows for wider trace spacing to maximize creepage and clearance distances.

Part Context

The IL717E belongs to the IsoLoop family, which distinguishes itself by using magnetic coupling rather than capacitive or optical methods. This architecture typically offers superior longevity and resistance to electromagnetic interference. The part serves as a bridge between low-voltage logic domains and higher-voltage industrial or medical interfaces, ensuring signal fidelity while maintaining electrical separation.
