The device supports data rates up to 150 Mbps with a propagation delay of 35 ns. It operates on a supply voltage range of 2.5 V to 5.5 V and provides an isolation voltage of 5 kVrms. The component utilizes capacitive coupling technology and is housed in a 16-pin SOIC package.

Digital Isolators Feature Summary

• Provides galvanic isolation via capacitive coupling technology for signal integrity
• Supports high-speed data transmission up to 150 Mbps without start-up initialization
• Features wide operating supply voltage compatibility ranging from 2.5 V to 5.5 V

Digital Isolators Applications

• Industrial automation systems requiring robust signal isolation
• Medical equipment needing high-voltage isolation safety
• Power metering applications for accurate data acquisition

Digital Isolators Procurement Notes

Verify the specific suffix 'A' against the manufacturer's latest datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure the SOIC-16 package dimensions align with your PCB footprint. Confirm that the 5 kVrms isolation rating meets the safety standards of your target application environment.

Digital Isolators Selection Notes

Select this component when high-speed communication up to 150 Mbps is required alongside strong isolation capabilities. The 3-forward/1-reverse channel configuration suits asymmetric data flow needs. Consider the 35 ns propagation delay for timing-sensitive circuits. The wide supply voltage range offers flexibility in power design compared to fixed-voltage alternatives.

Digital Isolators Part Context

This part belongs to the Si864x family of digital isolators, which are designed for general-purpose applications. The family emphasizes low power consumption and high reliability. The SI8641BD-A-IS specifically targets applications demanding higher speed than standard isolators while maintaining compact size and ease of integration into existing interface designs.

Digital Isolators Replacement Considerations

Check for SI8641BD-B-IS or SI8641BT-AS as potential variants within the same family, noting differences in isolation voltage or automotive qualification status.
