SI88422BC-ASR

Digital Isolators Overview

The SI88422BC-ASR is a general-purpose digital isolator from Skyworks Solutions, housed in a 16-SOIC package. It features two unidirectional channels with a data rate of 100 Mb/s and an insulation voltage of 5000 Vrms. The device operates on a supply voltage between 3 V and 5.5 V, with a maximum propagation delay of 18 ns. It supports an operating temperature range from -40°C to +125°C and offers a common-mode transient immunity of 40 kV/µs.

Digital Isolators Feature Summary

• Provides galvanic isolation for bidirectional signal transmission across separate power domains
• Utilizes capacitive coupling technology for high-speed digital signal integrity
• Designed for robust performance in harsh electromagnetic environments

Digital Isolators Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing patient isolation barriers
• Power electronics monitoring circuits

Digital Isolators Procurement Notes

Verify the specific suffix ASR indicates reel packaging when ordering. Confirm RoHS compliance status through official Skyworks documentation prior to integration. Ensure ESD handling protocols are followed during assembly due to moisture sensitivity classification. Cross-reference pinouts with the latest datasheet revision to avoid design errors.

Digital Isolators Selection Notes

Select this component for applications requiring unidirectional isolation with moderate data rates. The 16-pin SOIC footprint suits space-constrained designs. Consider the 5000 Vrms rating for high-voltage separation needs. Evaluate thermal management requirements given the wide operating temperature range and surface mount construction.
