IL 717TE

Digital Isolators Overview

The IL 717TE is a general-purpose digital isolator from the IsoLoop series, manufactured by NVE Corp/Isolation Products. It features four independent channels with a maximum data rate of 110 Mbps and a common-mode transient immunity (CMTI) of 100 kV/µs. The device provides 2500 Vrms isolation voltage and operates on a supply voltage range of 3 V to 5.5 V. It utilizes Giant Magnetoresistance (GMR) technology for signal transmission without an isolated power supply. The component is housed in a 16-SOIC package with a width of 7.50 mm. It supports unidirectional channel configurations and functions within an operating temperature range of -40°C to 125°C.

Digital Isolators Feature Summary

• Utilizes Giant Magnetoresistance (GMR) sensing technology for robust signal isolation
• Provides high common-mode transient immunity of 100 kV/µs across all channels
• Operates without requiring an isolated power supply for the receiver side
• Supports standard logic interface compatibility within specified voltage ranges

Digital Isolators Applications

• Industrial automation control systems
• Motor drive and power electronics interfaces
• Human-machine interface (HMI) connections
• General-purpose digital signal isolation in noisy environments

Digital Isolators Procurement Notes

Verify the specific suffix 'TE' to confirm the 16-SOIC surface-mount package configuration. Ensure the required channel directionality matches the internal pinout, as this variant may have fixed input/output assignments per channel. Confirm compliance with RoHS3 standards and check for any recent Package Change Notices (PCN) regarding ESD labeling or manufacturing site updates before finalizing procurement orders.

Digital Isolators Selection Notes

Select the IL 717TE when four-channel isolation is required with high-speed data transmission up to 110 Mbps. This part is suitable for applications demanding high CMTI to withstand rapid voltage changes in industrial settings. Choose this model over DIP variants if space-constrained PCB layouts necessitate a 16-SOIC footprint. Verify that the system voltage aligns with the 3 V to 5.5 V operating range and that the thermal environment stays within the -40°C to 125°C limit.

Digital Isolators Part Context

The IL 717TE belongs to the IsoLoop family of GMR-based digital isolators. Unlike optical or capacitive isolators, it does not require an isolated power supply, simplifying system design. The device is part of a broader lineup including 2-channel and different package options like DIP and TSSOP. It is designed for general-purpose use where reliable signal transmission across isolation barriers is critical.

Digital Isolators Replacement Considerations

Direct substitutes include other IL 717 variants such as IL 717T-3E, which shares similar electrical characteristics but may differ in packaging or suffix specifications. Cross-reference pinouts carefully when replacing with other 4-channel isolators, as channel directionality and power supply requirements may vary significantly between different isolation technologies.
