SI88220EC-ASR

Digital Isolators Overview

The SI88220EC-ASR is a general-purpose digital isolator manufactured by Skyworks Solutions, Inc. It features two unidirectional channels with a data rate of 100 Mb/s and an isolation voltage of 5000 Vrms. The device operates within a supply voltage range of 3 V to 5.5 V and exhibits a propagation delay of 18 ns. It supports a wide operating temperature range from -40°C to +125°C and utilizes a 16-SOIC package.

Digital Isolators Feature Summary

• Provides high-voltage electrical isolation between circuits using capacitive coupling technology.
• Supports bidirectional signal transmission through dedicated forward channel paths.
• Ensures reliable operation in harsh environments with extended industrial temperature ratings.

Digital Isolators Applications

• General-purpose digital isolation in industrial automation systems
• Isolating communication interfaces in embedded control units
• Protecting low-voltage logic circuits from high-voltage noise sources

Digital Isolators Procurement Notes

Verify the specific suffix ASR against official Skyworks documentation to confirm reel packaging and tape specifications. Ensure the 16-SOIC footprint matches your PCB layout constraints. Confirm that the 5000 Vrms isolation rating meets your system's safety requirements. Check for RoHS compliance status in the latest datasheet revision before finalizing procurement.

Digital Isolators Selection Notes

Select this component when a 5000 Vrms isolation barrier is required for unidirectional signals at speeds up to 100 Mb/s. It is suitable for designs needing a 16-pin SOIC form factor. Consider alternatives if bidirectional reverse channels or higher CMTI values are strictly necessary for the application environment.
