SI88342ED-AS

Digital Isolators Overview

The SI88342ED-AS is a high-speed digital isolator from Skyworks Solutions, featuring four unidirectional channels in a 24-pin SOIC package. It provides 5000 Vrms isolation voltage and supports data rates up to 100 Mb/s with a propagation delay of 18 ns. The device includes an integrated DC-DC converter for isolated power supply generation. Operating temperatures range from -40°C to +125°C, with a supply voltage range of 3 V to 5.5 V.

Digital Isolators Feature Summary

• Integrates a feedback-controlled DC-DC converter for isolated power delivery
• Provides robust capacitive coupling isolation technology
• Supports high common-mode transient immunity

Digital Isolators Applications

• Automotive electronic systems requiring galvanic isolation
• Industrial communication interfaces
• Power electronics control circuits

Digital Isolators Procurement Notes

Verify the specific suffix 'AS' against official Skyworks documentation to confirm pinout and feature set accuracy. Ensure compatibility with required isolation voltage standards for your application. Check for moisture sensitivity levels and reflow soldering profiles during procurement planning.

Digital Isolators Selection Notes

Select this component when bidirectional isolation is not required and an integrated isolated power source is needed. Compare the 5000 Vrms rating against system safety requirements. Consider the 24-SOIC footprint constraints and thermal management needs for high-temperature operation environments.

Digital Isolators Part Context

This part belongs to the Si8834x family of automotive-grade digital isolators. It shares architectural similarities with other variants like the SI88342EC-AS but differs in insulation voltage ratings and packaging options within the same series.

Digital Isolators Replacement Considerations

SI88342BD-ISR is listed as a similar alternative by distributors, though it lacks the integrated DC-DC converter. Verify functional equivalence carefully before substitution.
