IL 717-3

Digital Isolators 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.

Digital Isolators 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.

Digital Isolators 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.

Digital Isolators Part Context
