IL 717-3E

Overview

The IL717-3E is a high-speed digital isolator manufactured by NVE, featuring four channels with a typical data rate of 110 Mbps. It utilizes IsoLoop technology to provide an isolation voltage of 2500 Vrms and a common-mode transient immunity of 100 kV/µs. The device operates on a single 5.5V supply, supports surface mount installation in an 8-pin SOIC package, and functions within a temperature range of -40°C to 125°C.

Feature Summary

• Utilizes patented IsoLoop technology for reliable signal transmission across isolation barriers
• Provides high common-mode transient immunity to prevent noise-induced errors
• Supports unidirectional data flow with configurable transmit and receive channel configurations

Applications

• Industrial automation control systems requiring galvanic isolation
• Medical equipment needing certified safety isolation barriers
• Power electronics monitoring circuits

Procurement Notes

Verify the specific pin count configuration during procurement, as datasheets indicate potential discrepancies between 8-pin and 16-pin variants for this part number. Confirm that the supplier documentation explicitly references the 2500 Vrms isolation rating and 110 Mbps speed to ensure compliance with system requirements before finalizing orders.

Selection Notes

Select this component when designing systems requiring robust isolation against high-frequency noise and fast switching transients. The 100 kV/µs CMTI rating makes it suitable for noisy environments like motor drives. Ensure the chosen package variant matches the PCB footprint constraints and thermal management needs of the target application.

Part Context

This device belongs to the IL series of digital isolators from NVE, which are designed to replace traditional optocouplers. The series emphasizes higher speed, lower power consumption, and improved reliability through solid-state magnetic coupling rather than optical components.
