SI88322EC-IS

Digital Isolators Overview

The SI88322EC-IS is a Skyworks digital isolator featuring two unidirectional channels in a 20-SOIC package. It operates on a 3 V to 5.5 V supply with a data rate of 100 Mb/s and isolation voltage of 3750 Vrms. The device exhibits a propagation delay of 18 ns, rise/fall times of 2.5 ns, and pulse width distortion of 4.5 ns. It supports an operating temperature range from -40°C to +125°C and includes AEC-Q100 qualification.

Digital Isolators Feature Summary

• Capacitive coupling technology for high-speed signal transmission
• Integrated DC-DC converter capability within the ISOvolt series
• AEC-Q100 automotive grade qualification for reliability

Digital Isolators Applications

• Industrial automation systems requiring robust signal isolation
• Automotive electronic control units (ECUs) meeting strict standards
• Motor drive circuits needing reliable gate driver isolation

Digital Isolators Procurement Notes

Verify the specific suffix 'IS' against official Skyworks documentation to confirm the inclusion of integrated DC-DC functionality versus standard isolation-only variants. Ensure the 20-SOIC package dimensions match PCB footprint requirements. Confirm AEC-Q100 compliance if automotive application is intended. Check moisture sensitivity level handling procedures during assembly.

Digital Isolators Selection Notes

Select this component when bidirectional isolation is not required, as it features unidirectional channels only. Consider the integrated DC-DC option if power delivery across the isolation barrier is needed without external components. Compare CMTI ratings against noise environments. Evaluate thermal performance within the specified -40°C to +125°C range for harsh industrial or automotive conditions.

Digital Isolators Part Context

Part of the Si8832x ISOvolt family, designed to replace optocouplers with smaller size and lower power consumption. Utilizes CMOS technology for enhanced reliability and speed compared to traditional magnetic or optical isolation methods.
