SI88341BC-IS

Digital Isolators Overview

The SI88341BC-IS is a general-purpose digital isolator manufactured by Skyworks Solutions Inc. It features four channels with a unidirectional configuration, providing 5000Vrms isolation voltage. The device supports data rates up to 100Mbps and offers a common-mode transient immunity of 40kV/µs. Propagation delays are specified at 18ns for high-to-low and 23ns for low-to-high transitions. It operates within a supply voltage range of 3V to 5.5V and functions across temperatures from -40°C to +125°C. The component is housed in a 24-SOIC package.

Digital Isolators Feature Summary

• Integrates capacitive coupling technology for robust signal transmission across isolation barriers
• Includes an integrated DC-DC converter to provide isolated power delivery
• Supports bidirectional communication through dedicated forward and reverse channel configurations

Digital Isolators Applications

• Industrial automation control systems requiring galvanic isolation

• Medical equipment needing high-voltage safety compliance

Digital Isolators Procurement Notes

Verify the specific suffix 'IS' against official Skyworks documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the 24-SOIC form factor. Check current lifecycle status as some variants may be recommended for new design only. Confirm moisture sensitivity levels prior to assembly processing.

Digital Isolators Selection Notes

Select this component when high isolation voltage and integrated power transfer are required in a single package. Consider the 100Mbps data rate limit for application bandwidth requirements. Evaluate the 24-pin SOIC footprint constraints against available board space. Compare propagation delay characteristics against system timing budgets to ensure signal integrity.
