IL 717-3

Overview

The IL717-3 is a high-speed digital isolator from NVE, featuring four channels with a maximum data rate of 110 Mbps. It operates on a single 5.5V supply and provides 2500 Vrms isolation voltage. The device utilizes IsoLoop technology for signal transmission across the isolation barrier. It supports surface mount installation in a 16-pin SOIC package. The component functions within an operating temperature range of -40°C to +125°C. Key electrical parameters include a typical propagation delay of 18ns and a rise time of 4ns. It offers common-mode transient immunity of 100kV/µs.

Feature Summary

• Utilizes patented IsoLoop technology for galvanic isolation without magnetic cores
• Provides unidirectional signal transmission with three transmit and one receive channel configuration
• Supports high-speed data communication up to 110 Mbps
• Features robust common-mode transient immunity for noisy environments

Applications

• Industrial automation systems requiring isolated communication
• Medical equipment needing reinforced isolation barriers
• Power electronics control circuits
• Test and measurement instrumentation

Procurement Notes

Verify the specific suffix (e.g., -3E) against your design requirements, as it may indicate packaging or certification variations. Confirm the pinout matches the 16-SOIC footprint. Ensure the isolation voltage rating meets system safety standards. Check for RoHS compliance if required by your manufacturing process. Validate the operating temperature range for your specific environmental conditions.

Selection Notes

Select this component when high-speed unidirectional isolation is required. Consider the 16-pin package size for PCB layout constraints. Evaluate the 2500 Vrms isolation level against system safety regulations. Compare the 110 Mbps speed with other available options if higher throughput is needed. Assess the power consumption characteristics relative to system efficiency goals.

Part Context

The IL717 series belongs to NVE's IsoLoop family of digital isolators. These devices replace traditional optocouplers in many applications. They offer superior performance in speed and reliability. The series includes various channel configurations and isolation ratings. This specific model focuses on high-speed unidirectional data transfer.

Replacement Considerations

Check for direct substitutes within the IL717 series with different suffixes. Verify compatibility with existing circuit designs before substitution. Ensure replacement parts meet the same isolation and speed specifications.
