SI8655BD-AS

Digital Isolators Overview

The SI8655BD-AS is a general-purpose digital isolator from Skyworks Solutions, Inc. It features five independent channels with a maximum data rate of 150 Mbps and a common-mode transient immunity (CMTI) of 35 kV/µs. The device provides 5000 Vrms isolation voltage and operates on a wide supply voltage range of 2.5 V to 5.5 V. Packaged in a 16-SOIC footprint measuring 0.295 inches (7.50 mm) in width, it requires no start-up initialization.

Digital Isolators Feature Summary

• High-speed operation supporting data rates up to 150 Mbps
• Wide operating supply voltage range from 2.5 V to 5.5 V
• No start-up initialization required for immediate functionality
• Provides robust 5000 Vrms isolation capability

Digital Isolators Applications

• Automotive systems requiring high-voltage isolation
• Industrial automation and control circuits
• Power supply monitoring and feedback loops

Digital Isolators Procurement Notes

Verify the specific suffix 'AS' against official Skyworks documentation to confirm automotive-grade qualification status. Ensure the package type matches the 16-SOIC specification. Cross-reference the datasheet revision date to confirm compatibility with current design requirements. Confirm RoHS compliance details directly from the manufacturer's certificate.

Digital Isolators Selection Notes

Select this component when five isolated channels are required within a single package. Consider the 150 Mbps speed limit for signal integrity needs. Evaluate the 35 kV/µs CMTI rating against noise environments. Verify that the 2.5–5.5 V supply range aligns with system power rails. Check thermal performance requirements for the SOIC package.

Digital Isolators Part Context

This part belongs to the Skyworks Si86xx family of ultra-low-power CMOS digital isolators. The family offers substantial data rates, propagation delay, power efficiency, size, and reliability advantages over traditional optocouplers. The SI8655 variant specifically provides five-channel isolation capabilities.

Digital Isolators Replacement Considerations

Consult the official Skyworks replacement guide for direct equivalents. Verify pinout compatibility before substitution. Ensure isolation voltage ratings meet or exceed original specifications.
