SI88320BD-IS

Digital Isolators Overview

The SI88320BD-IS is a Skyworks Solutions digital isolator featuring two unidirectional channels and an integrated DC-DC converter. It operates within a supply voltage range of 3 V to 5.5 V, supporting data rates up to 100 Mb/s with a propagation delay of 18 ns. The device provides 5000 Vrms isolation via capacitive coupling and includes a shutdown function. Packaged in a 20-SOIC (Wide) surface-mount format, it functions reliably between -40°C and +125°C.

Digital Isolators Feature Summary

• Integrates a high-efficiency DC-DC converter for isolated power generation
• Provides robust signal isolation through capacitive coupling technology
• Includes a dedicated shutdown pin for active power management

Digital Isolators Applications

• Industrial automation control systems
• Medical equipment requiring galvanic isolation
• Power electronics and motor drives
• General-purpose communication interfaces

Digital Isolators Procurement Notes

Verify the specific suffix 'IS' corresponds to the tape-and-reel packaging configuration rather than tube packaging. Confirm that the component meets AEC-Q100 qualification requirements if automotive applications are intended. Ensure the design accounts for the NRND status by evaluating long-term availability constraints before finalizing procurement plans.

Digital Isolators Selection Notes

Select this component when a compact solution combining dual-channel isolation with integrated power conversion is required. It is suitable for designs needing high common-mode transient immunity and low propagation delay. Consider the 20-pin wide SOIC footprint for thermal dissipation and PCB layout compatibility compared to smaller packages.

Digital Isolators Part Context

This part belongs to the Si883xx family of digital isolators from Skyworks Solutions. It shares core architectural features with other models in the series but differs in channel count and package type. The SI88320BD-IS specifically targets applications requiring two isolated data paths alongside on-chip power regulation.

Digital Isolators Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the NRND status, alternative components should be evaluated based on matching isolation voltage, channel count, and package dimensions.
