IL 717

Digital Isolators Overview

The IL717 is a four-channel digital isolator from the IsoLoop series, utilizing Giant Magnetoresistance (GMR) technology. It supports data rates up to 110 Mbps with a maximum propagation delay of 15 ns and typical rise/fall times of 1 ns. The device offers 2500 Vrms isolation voltage and operates on a single supply voltage ranging from 3V to 5.5V. It features a channel configuration of three inputs and one output, housed in a 16-pin SOIC package. The component functions within an operating temperature range of -40°C to +125°C.

Digital Isolators Feature Summary

• Employs GMR sensor technology for high-speed signal transmission without magnetic cores
• Provides robust electrical isolation between input and output sides
• Supports unidirectional data flow across multiple channels

Digital Isolators Applications

• Industrial automation control systems
• Medical equipment signal isolation
• Power electronics gate drive circuits

Digital Isolators Procurement Notes

Verify the specific suffix code (e.g., E, T, V) to confirm package type, temperature rating, and isolation level. Confirm RoHS compliance status as older variants may differ. Ensure the selected variant matches the required channel count and pinout for the target PCB layout. Cross-reference official datasheets for exact electrical limits before integration.

Digital Isolators Selection Notes

Select based on required isolation voltage and operating temperature range. The standard IL717 provides 2500 Vrms isolation suitable for general applications. Variants like the V-series offer higher reinforced isolation ratings. Consider the package style (SOIC vs DIP) and thermal requirements when choosing between standard and extended temperature options.

Digital Isolators Part Context

The IL717 belongs to NVE's IsoLoop family of digital isolators. This series distinguishes itself by using GMR sensors instead of traditional capacitive or optical methods. The family includes various channel counts and package configurations designed for high-reliability industrial and medical environments requiring galvanic isolation.

Digital Isolators Replacement Considerations

IL717-3E: Surface mount variant with identical electrical characteristics but specific packaging details. IL717TE: Tube-packaged version of the 16-SOIC device. Verify pin compatibility and isolation ratings when substituting.
