SI88320ED-AS

Digital Isolators Overview

The SI88320ED-AS is a Skyworks Solutions digital isolator housed in a 20-SOIC package. It features two unidirectional channels with a data rate of 100 Mb/s and an insulation voltage of 5000 Vrms. The device operates on a supply voltage between 3 V and 5.5 V, drawing 9.5 mA. Key electrical parameters include an 18 ns propagation delay, 2.5 ns rise/fall times, and 4.5 ns pulse width distortion. It supports a wide operating temperature range from -40°C to +125°C.

Digital Isolators Feature Summary

• Provides high-speed digital isolation for bidirectional signal transmission across isolated boundaries
• Integrates true automotive process design for robust manufacturing and production test support
• Offers high common-mode transient immunity to maintain signal integrity in noisy environments

Digital Isolators Applications

• Automotive electronic control units requiring galvanic isolation
• Industrial communication interfaces such as CAN bus and LIN bus
• Power conversion systems needing feedback loop isolation

Digital Isolators Procurement Notes

Verify the specific suffix 'ED-AS' against official Skyworks documentation to confirm pinout and packaging details. Confirm RoHS compliance status through current datasheets. Check for moisture sensitivity levels if reflow soldering is planned. Ensure the source provides valid traceability for automotive-grade requirements.

Digital Isolators Selection Notes

Select this component when dual-channel isolation is required within a 20-pin SOIC footprint. Compare power consumption against alternatives if battery efficiency is critical. Verify that the 100 Mb/s speed meets system timing constraints. Ensure the 5000 Vrms isolation rating satisfies safety standards for the target application voltage.

Digital Isolators Part Context

This part belongs to the Si8832x family of general-purpose digital isolators. It shares architectural similarities with other members like the SI88321ED-AS but differs in channel configuration or specific electrical characteristics. The family leverages silicon dioxide isolation technology for reliable performance.

Digital Isolators Replacement Considerations

Direct substitutes may include SI88321ED-AS or SI88420ED-AS, provided channel counts and pinouts match. Verify functional equivalence before substitution. Cross-reference with SI88320ED-ASR for reel-based packaging needs.
