SI88222BD-ISR

Digital Isolators Overview

The SI88222BD-ISR is a Skyworks Solutions digital isolator featuring two channels with unidirectional signal paths. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 100 Mb/s. The device provides an insulation voltage of 5000 Vrms and exhibits a propagation delay of 23 ns. It utilizes SOIC-16 packaging for surface mount installation.

Digital Isolators Feature Summary

• Integrates a secondary sensing feedback-controlled DC-DC converter
• Provides high-speed isolation with 40kV/µs common-mode transient immunity

Digital Isolators Applications

• Industrial automation systems
• Medical equipment requiring galvanic isolation
• General-purpose isolated communication interfaces

Digital Isolators Procurement Notes

Verify the specific suffix 'ISR' against official Skyworks documentation to confirm tape-and-reel packaging configuration. Confirm lifecycle status, as this component may be marked as Not Recommended for New Designs (NRND). Ensure compatibility with existing board layouts before procurement.

Digital Isolators Selection Notes

Select this component when integrated power conversion is required alongside signal isolation. It suits applications needing high common-mode transient immunity and low propagation delay. Verify that the SOIC-16 package dimensions meet the target PCB constraints.

Digital Isolators Part Context

This part belongs to the SI8822x series of digital isolators from Skyworks Solutions. These devices combine capacitive coupling technology with on-chip DC-DC converters to eliminate the need for external isolation transformers or separate power supplies across the isolation barrier.
