SI8641BT-AS2R

Digital Isolators Overview

The SI8641BT-AS2R is an automotive-grade digital isolator from the Si864x series, manufactured by Skyworks Solutions. It features four channels configured as three unidirectional forward and one reverse channel. The device utilizes capacitive coupling technology to provide electrical isolation with a rated insulation voltage of 5000 Vrms. It supports data rates up to 150 Mb/s and operates within a supply voltage range of 2.5 V to 5.5 V. Key electrical parameters include a propagation delay of 8 ns, rise/fall times of 4 ns, and a typical operating supply current of 5.2 mA. It is qualified under AEC-Q100 standards for automotive applications.

Digital Isolators Feature Summary

• Automotive qualification compliant with AEC-Q100 standards
• Capacitive coupling isolation technology
• High common-mode transient immunity

Digital Isolators Applications

• Automotive electronic control units
• Inverter gate drive circuits
• Industrial communication interfaces

Digital Isolators Procurement Notes

Verify the specific suffix 'AS2R' indicates reel packaging rather than tube packaging when ordering. Confirm that the component meets the required AEC-Q100 reliability standards for your specific automotive application environment. Ensure compatibility with the SOIC-16 surface mount package dimensions during PCB layout.

Digital Isolators Selection Notes

Select this part when high-speed digital isolation is required in automotive environments. The 3-forward/1-reverse channel configuration suits asymmetric data transmission needs. Consider the 5000 Vrms insulation rating for safety-critical barriers. Evaluate power consumption against system constraints given the 5.2 mA operating current.

Digital Isolators Part Context

This component belongs to the Si864x family of digital isolators. It shares core specifications with the SI8641BT-AS2 but differs in packaging format. The 'R' suffix typically denotes tape and reel packaging suitable for automated assembly processes.

Digital Isolators Replacement Considerations

SI8641BT-AS2 is the tube-packaged equivalent. Verify if the change from reel to tube affects handling procedures without altering electrical performance.
