SI8663ED-B-IS

Digital Isolators Overview

The SI8663ED-B-IS is a Skyworks Solutions digital isolator featuring six channels with three forward and three reverse unidirectional paths. It utilizes capacitive coupling technology to provide an insulation voltage of 5000 Vrms. The device supports data rates up to 150 Mb/s with a typical propagation delay of 8 ns. It operates within a supply voltage range of 2.375 V to 5.5 V and functions across a temperature range of -40°C to +125°C. Packaged in a wide SOIC-16, it offers high common-mode transient immunity.

Digital Isolators Feature Summary

• Provides galvanic isolation via capacitive coupling technology for robust signal transmission.
• Features six independent channels configured as three forward and three reverse unidirectional paths.
• Delivers high common-mode transient immunity to maintain signal integrity in noisy environments.

Digital Isolators Applications

• Industrial automation systems requiring reliable signal isolation
• Power monitoring circuits in energy management applications
• General-purpose digital isolation in mixed-signal environments

Digital Isolators Procurement Notes

Verify the specific suffix 'ED' against official Skyworks documentation to confirm the wide SOIC package and 5 kV rating. Ensure compatibility with AEC-Q100 requirements if automotive qualification is needed, though this specific part number is primarily general purpose. Confirm moisture sensitivity level handling during storage and assembly processes.

Digital Isolators Selection Notes

Select this component when high-voltage isolation of 5000 Vrms is required alongside high-speed data transmission at 150 Mb/s. The wide SOIC-16 package facilitates easier PCB layout compared to narrow variants. Consider the unidirectional channel configuration for applications where signal flow is strictly one-way between isolated domains.

Digital Isolators Part Context

This part belongs to the Si866x family of digital isolators from Skyworks Solutions. The family is characterized by its use of silicon dioxide (SiO2) isolation technology, which provides superior reliability and performance compared to traditional polymer-based solutions. The SI8663 variant specifically addresses multi-channel isolation needs.

Digital Isolators Replacement Considerations

SI8663BD-AS: Automotive qualified version with similar electrical characteristics but standard SOIC package.
