CMOS digital isolator SKYWORKS SI8642AB-B-IS1 offering fast data rates and wide supply voltage range for industrial

Skyworks Si86xx Digital Isolators

Skyworks' Si86xx family of ultra-low-power digital isolators are CMOS devices designed to provide robust, high-speed data isolation. They offer significant advantages over legacy isolation technologies in terms of data rate, propagation delay, power consumption, size, and reliability. These isolators maintain stable operating parameters across wide temperature ranges and throughout their service life, simplifying design and ensuring uniform performance. Key features include Schmitt trigger inputs for high noise immunity, support for data rates up to 1 Mbps, and enable inputs for output control. All devices are safety certified and support withstand ratings up to 2.5 kVRMS. Automotive-grade versions are available, built with automotive-specific manufacturing flows for enhanced robustness and low defectivity.
