SI88320BD-AS

Digital Isolators Overview

The SI88320BD-AS is a Skyworks Solutions digital isolator featuring two unidirectional channels in a 20-SOIC package. It supports data rates up to 100 Mb/s with an isolation voltage of 5000 Vrms and common-mode transient immunity of 40 kV/µs. Operating on a supply voltage between 3 V and 5.5 V, it draws 7.3 mA typical current. The device exhibits a propagation delay of 18 ns and rise/fall times of 2.5 ns. It functions within a temperature range of -40°C to +125°C without a shutdown feature.

Digital Isolators Feature Summary

• Provides galvanic isolation for bidirectional signal transmission across high-voltage barriers
• Ensures signal integrity through high common-mode transient immunity capabilities
• Delivers precise timing performance with low propagation delay and pulse width distortion

Digital Isolators Applications

• Industrial automation control systems

• Medical device signal isolation

Digital Isolators Procurement Notes

Verify the specific suffix designation against official Skyworks documentation to confirm pinout compatibility and electrical specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration into surface-mount assembly processes.

Digital Isolators Selection Notes

Select this component when unidirectional isolation is required for two-channel applications. Ensure the 20-SOIC footprint aligns with PCB layout constraints. Validate that the 5000 Vrms isolation rating meets system safety standards and that the 100 Mb/s speed suffices for the target communication protocol.
