SI8655BA-AUR

Digital Isolators Overview

The SI8655BA-AUR is a Skyworks Solutions automotive-grade digital isolator featuring five forward channels with unidirectional signal transmission. It utilizes capacitive coupling technology to provide 1000 Vrms isolation voltage and supports data rates up to 150 Mb/s. The device operates within a supply voltage range of 2.5 V to 5.5 V and functions across an extended temperature range from -40°C to +125°C. Packaged in a 16-SSOP form factor, it meets AEC-Q100 qualification standards for automotive applications.

Digital Isolators Feature Summary

• Provides galvanic isolation via capacitive coupling technology
• Supports high-speed data transmission at 150 Mb/s
• Qualified for automotive environments under AEC-Q100 standards
• Features unidirectional signal flow across five independent channels

Digital Isolators Applications

Digital Isolators Procurement Notes

Verify the specific suffix 'AUR' corresponds to the tape-and-reel packaging configuration rather than tube packaging. Confirm that the AEC-Q100 qualification status aligns with your automotive project requirements. Ensure the 16-SSOP footprint matches your PCB layout constraints. Cross-reference the manufacturer's latest datasheet for any updates on moisture sensitivity levels or recommended soldering profiles.

Digital Isolators Selection Notes

Select this component when five isolated channels are required for unidirectional signals in automotive or industrial settings. Consider the 1000 Vrms isolation rating against system voltage requirements. Evaluate the 150 Mb/s data rate capability against signal timing constraints. Compare power consumption characteristics if low-power operation is critical for the application design.

Digital Isolators Part Context

This part belongs to the Si865x series of digital isolators from Skyworks Solutions. The series offers various channel configurations and isolation ratings tailored for robust signal transmission across isolation barriers. The SI8655 variant specifically addresses applications needing multiple isolated outputs with high reliability and speed.

Digital Isolators Replacement Considerations

Publicly documented parameter-equivalent substitutes include SI8655BA-AU and SI8655BA-B-IU. Verify package compatibility and pinout alignment before substitution. Ensure replacement parts meet the same AEC-Q100 automotive qualification standards.
