Digital Isolator Device SKYWORKS SI8631AB-B-IS with 1 Mbps Data Rate and 2.5 kVRMS Isolation Rating
Product Overview
Skyworks' Si86xx family of ultra-low-power digital isolators are CMOS devices designed to provide robust, high-speed data isolation. They offer significant advantages in data rate, propagation delay, power consumption, size, and reliability compared to traditional isolation technologies. 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, no start-up initialization required, and support for data rates up to 1 Mbps. All devices are safety certified and support withstand ratings up to 2.5 kVRMS, with automotive-grade options available for demanding applications.
