SI8662BB-AS1R

Digital Isolators Overview

The SI8662BB-AS1R is a six-channel general-purpose digital isolator manufactured by Skyworks Solutions Inc. It features unidirectional signal transmission with four forward and two reverse channels. The device utilizes capacitive coupling technology to provide electrical isolation with an insulation voltage of 2500 Vrms. It supports data rates up to 1 Mb/s and operates within a supply voltage range of 2.5 V to 5.5 V. Key timing parameters include a propagation delay of 35 ns, rise/fall times of 4 ns, and a pulse width capability of 250 ns. The component is housed in a 16-SOIC package and is qualified under AEC-Q100 standards for automotive applications.

Digital Isolators Feature Summary

• Six-channel unidirectional digital isolation using capacitive coupling technology
• Automotive-grade qualification compliant with AEC-Q100 standards
• General-purpose design supporting standard logic interface protocols

Digital Isolators Applications

• Automotive electronic control unit (ECU) isolation
• Industrial communication bus isolation
• Power supply feedback loop isolation

Digital Isolators Procurement Notes

Verify the specific suffix AS1R against official Skyworks documentation to confirm reel packaging specifications and tape-and-reel dimensions. Ensure that the AEC-Q100 automotive qualification aligns with target application requirements. Cross-reference the SOIC-16 package outline drawings with PCB footprint designs to guarantee mechanical compatibility during assembly.

Digital Isolators Selection Notes

Select this component when unidirectional isolation is required for automotive or industrial systems. The 1 Mb/s data rate suits lower-speed control signals rather than high-bandwidth data links. Consider the 2500 Vrms isolation barrier for basic safety requirements. Evaluate the 35 ns propagation delay against system timing constraints before finalizing the design.

Digital Isolators Part Context

This part belongs to the Si86xx series of digital isolators from Skyworks Solutions. The series offers various channel counts and speed grades. The SI8662 variant specifically provides six channels in a single package, consolidating multiple isolation barriers into one compact solution compared to discrete components.

Digital Isolators Replacement Considerations

Direct replacements must match the 6-channel unidirectional configuration and 1 Mb/s speed. Verify equivalent AEC-Q100 qualification if automotive use is mandatory. Check pinout compatibility for SOIC-16 packages to ensure drop-in replacement feasibility without PCB redesign.
