SI88220BD-ASR

Digital Isolators Overview

The SI88220BD-ASR is a Skyworks Solutions digital isolator featuring two unidirectional channels in a 16-pin SOIC package. It supports data rates up to 100 Mb/s with an isolation voltage of 5000 Vrms and a typical common-mode transient immunity of 40 kV/µs. Operating on a supply voltage between 3 V and 5.5 V, it draws 7.2 mA and functions within a temperature range of -40°C to +125°C.

Digital Isolators Feature Summary

• Provides robust galvanic isolation for signal transmission between circuits
• Capacitive coupling technology ensures high reliability and low power consumption
• High common-mode transient immunity protects against noise interference

Digital Isolators Applications

• Industrial automation systems requiring isolated I/O interfaces
• Programmable logic controllers (PLCs) for input isolation
• Motor drive control circuits needing reliable signal separation

Digital Isolators Procurement Notes

Verify the specific suffix ASR against official Skyworks documentation to confirm tape-and-reel packaging requirements. Ensure the selected variant matches the required operating temperature range and channel configuration for your specific design constraints before finalizing procurement.

Digital Isolators Selection Notes

Select this component when designing systems requiring 5000 Vrms isolation with moderate speed requirements. The 100 Mb/s data rate suits many industrial applications. Verify that the 16-pin SOIC footprint fits the PCB layout and that the 3 V to 5.5 V supply range aligns with the system power architecture.

Digital Isolators Part Context

This device belongs to the Si88xx ISOvolt series, which integrates digital isolation with optional DC-DC converter capabilities in some variants. The series targets industrial and automotive markets, offering a CMOS-based alternative to traditional optocouplers with improved performance and smaller form factors.

Digital Isolators Replacement Considerations

Check Skyworks datasheets for direct pin-compatible alternatives within the Si8822x family. Verify if other suffixes like BD or BC meet the same electrical specifications and packaging requirements.
