SI8641ET-IS

Digital Isolators Overview

The SI8641ET-IS is a four-channel digital isolator from the Si864x series, manufactured by Skyworks Solutions Inc. It features capacitive coupling technology with an insulation voltage of 5000 Vrms and supports data rates up to 150 Mb/s. The device operates within a supply voltage range of 2.375 V to 5.5 V and exhibits a propagation delay of 8 ns. It is housed in a 16-pin SOIC-wide package and functions unidirectionally across a temperature range of -40°C to +125°C.

Digital Isolators Feature Summary

• Provides high-voltage isolation via capacitive coupling for signal integrity
• Supports high-speed data transmission at rates up to 150 Mb/s
• Features low propagation delay for precise timing applications
• Operates with wide supply voltage flexibility

Digital Isolators Applications

• Industrial automation control systems
• Medical equipment signal isolation
• Power metering and energy management
• Automotive electronics interfaces

Digital Isolators Procurement Notes

Verify the specific suffix 'IS' corresponds to the standard tube packaging configuration as indicated in distributor listings. Confirm that the 5000 Vrms insulation rating aligns with your system's safety requirements. Ensure the SOIC-wide 16-pin footprint matches your PCB layout constraints before finalizing procurement orders.

Digital Isolators Selection Notes

Select this component when unidirectional isolation is required for multiple channels. It is suitable for designs needing robust noise immunity without active shutdown controls. Consider the 150 Mb/s speed limit for bandwidth requirements. The wide operating temperature range makes it appropriate for harsh environments.

Digital Isolators Part Context

This part belongs to the Si864x family of ultra-low power digital isolators. It shares architectural similarities with other variants like the SI8640 and SI8641BA but differs in channel configuration and insulation ratings. The ET-IS designation specifies the commercial grade and packaging type within this broader product line.

Digital Isolators Replacement Considerations

The SI8641ET-AS2 is an automotive-grade alternative within the same series offering similar electrical characteristics. Verify if AEC-Q100 qualification is necessary for your application. Other family members may require different pin configurations or insulation levels.
