SI88343BC-IS

Digital Isolators Overview

The SI88343BC-IS is a Skyworks digital isolator featuring four channels in a 24-SOIC package. It supports unidirectional signal transmission at data rates up to 100 Mb/s with a propagation delay of 18 ns. The device provides an insulation voltage of 5000 Vrms and operates within a supply voltage range of 3 V to 5.5 V. It includes one forward channel and three reverse channels, with rise and fall times of 2.5 ns. The component functions reliably across an operating temperature range from -40°C to +125°C.

Digital Isolators Feature Summary

• Integrates capacitive coupling technology for high-speed digital isolation
• Provides robust common-mode transient immunity for noise-sensitive environments
• Features integrated DC-DC converter capability for isolated power delivery

Digital Isolators Applications

• Industrial automation control systems
• Medical equipment signal isolation
• Power supply feedback loops

Digital Isolators Procurement Notes

Verify the specific suffix 'IS' confirms the inclusion of the integrated DC-DC converter functionality, as this distinguishes it from non-converter variants like the 'AS'. Ensure the SOIC-24 package dimensions match your PCB footprint requirements. Confirm RoHS compliance status through official manufacturer documentation prior to integration into regulated products.

Digital Isolators Selection Notes

Select this model when both high-speed data isolation and isolated power generation are required in a single component. Compare against the SI88343BC-AS if only signal isolation without power conversion is needed. Evaluate the 5000 Vrms insulation rating against system safety standards. Consider the 100 Mb/s data rate limit for bandwidth requirements.
