SI8641AB-B-IS1R

Digital Isolators Overview

The SI8641AB-B-IS1R is a Skyworks Solutions digital isolator featuring four channels with three unidirectional forward and one reverse path. It utilizes capacitive coupling for signal transmission, offering an insulation voltage of 2500 Vrms. The device supports data rates up to 1 Mb/s with a propagation delay of 35 ns. Operating within a supply voltage range of 2.5 V to 5.5 V, it is housed in a 16-pin SOIC-Narrow package. Certified under AEC-Q100 standards, it functions reliably between -40°C and +125°C.

Digital Isolators Feature Summary

• Capacitive coupling technology provides robust isolation without magnetic interference
• AEC-Q100 qualification ensures reliability for automotive electronic applications
• Integrated shutdown functionality allows for power management control

Digital Isolators Applications

• Automotive electronics systems requiring high-voltage isolation

Digital Isolators Procurement Notes

Verify the specific suffix IS1R corresponds to the required tape and reel packaging configuration. Confirm that the AEC-Q100 automotive grade certification aligns with your project's environmental and reliability standards. Ensure the SOIC-Narrow-16 footprint matches your PCB layout constraints before finalizing procurement orders.

Digital Isolators Selection Notes

Select this component when high common-mode transient immunity is critical for noise-sensitive environments. The 1 Mbps data rate suits moderate-speed communication links where low latency is not the primary constraint. Consider the 2500 Vrms isolation barrier for applications demanding significant potential difference separation between circuit domains.
