SI86SO21BC-IS

Digital Isolators Overview

The SI86SO21BC-IS is a Skyworks Solutions digital isolator featuring two unidirectional channels with inverting outputs. It utilizes capacitive coupling technology to provide 6000 VRMS isolation voltage, ensuring robust signal transmission across high-voltage barriers. The device supports data rates up to 150 Mbps and operates within a supply voltage range of 2.25 V to 5.5 V. Packaged in an SSO-8 format, it is designed for applications requiring high-speed data isolation with minimal propagation delay.

Digital Isolators Feature Summary

• Provides 6000 VRMS insulation voltage for enhanced safety in high-voltage environments
• Supports high-speed data transmission up to 150 Mbps without start-up initialization
• Features inverting output logic for flexible interface compatibility
• Operates on a wide supply voltage range from 2.25 V to 5.5 V

Digital Isolators Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing high-reliability signal separation

• Communication gateways isolating high-voltage domains

Digital Isolators Procurement Notes

Verify the specific suffix 'BC' confirms the inverting output configuration and 6000 VRMS rating against the official datasheet. Ensure the SSO-8 package matches your PCB footprint requirements. Confirm AEC-Q100 qualification if automotive compliance is necessary. Check moisture sensitivity levels for proper storage and reflow soldering profiles.

Digital Isolators Selection Notes

Select this component when 6000 VRMS isolation is mandatory rather than standard 3750 Vrms options. The inverting output characteristic requires checking logic compatibility with downstream receivers. Consider the SSO-8 package width constraints compared to standard SOIC-8 variants. Verify that the 150 Mbps speed meets system timing requirements without excessive jitter.
