SI8717BC-A-IS

Digital Isolators Overview

The SI8717BC-A-IS is a single-channel digital isolator from Skyworks Solutions, designed as a drop-in replacement for optocouplers. It features capacitive coupling technology with a 3.75 kVrms isolation voltage and supports data rates up to 15 Mbps. The device operates within a supply voltage range of 2.5 V to 5.5 V, drawing a typical quiescent current of 1.5 mA. It offers a common-mode transient immunity of 35 kV/µs and a propagation delay of 60 ns. Packaged in an 8-SOIC format, it functions reliably across an extended temperature range from -40°C to +125°C.

Digital Isolators Feature Summary

• Capacitive coupling architecture provides robust signal isolation without optical components
• Pin-compatible design enables direct drop-in replacement for legacy optocouplers
• High common-mode transient immunity ensures reliable operation in noisy environments

Digital Isolators Applications

• Industrial automation control systems
• Power supply feedback loops
• General-purpose isolated communication interfaces

Digital Isolators Procurement Notes

Verify the specific suffix 'A-IS' corresponds to the SOIC-8 package variant rather than the DIP or Tape & Reel options. Confirm that the component meets AEC-Q100 qualification requirements if automotive application is intended. Ensure the ordering information matches the exact datasheet revision to avoid pinout discrepancies.

Digital Isolators Selection Notes

Select this component when replacing traditional optocouplers to achieve higher speed and lower power consumption. The single-channel configuration suits applications requiring one isolated signal path. Consider the 15 Mbps data rate limit and 3.75 kVrms isolation barrier for system compatibility.
