SI88320ED-ISR

Digital Isolators Overview

The SI88320ED-ISR is a Skyworks Solutions digital isolator featuring two unidirectional channels and an integrated DC-DC converter. It provides 5000 Vrms isolation via capacitive coupling with a data rate of 100 Mb/s. Operating on a 3 V to 5.5 V supply, it exhibits 18 ns propagation delay and 2.5 ns rise/fall times. The device supports -40°C to +125°C operation in a SOIC-Wide-20 package.

Digital Isolators Feature Summary

• Integrates a high-efficiency isolated DC-DC converter for power delivery across the isolation barrier
• Utilizes advanced CMOS technology for superior reliability compared to traditional optocouplers
• Provides robust noise immunity through high common-mode transient rejection capabilities

Digital Isolators Applications

• Industrial automation systems requiring reliable signal isolation
• Inverter and motor drive control circuits
• Programmable logic controller (PLC) input/output modules

Digital Isolators Procurement Notes

Verify the specific suffix 'ISR' confirms the SOIC-Wide-20 surface-mount package and reel packaging format. Ensure the design accounts for the integrated DC-DC converter requirements and thermal dissipation limits within the specified operating temperature range. Confirm AEC-Q100 qualification status if automotive compliance is required.

Digital Isolators Selection Notes

Select this component when a compact solution combining signal isolation and isolated power generation is necessary. The 100 Mb/s speed suits general-purpose applications, while the wide temperature range ensures stability in harsh industrial environments. Consider the channel count and voltage ratings relative to system isolation requirements.
