Skyworks' Si864x family of ultra-low-power, quad-channel digital isolators offer superior data rate, propagation delay, power consumption, size, and reliability compared to traditional isolation technologies. These CMOS devices maintain stable operating parameters across wide temperature ranges and throughout their service life, simplifying design and ensuring uniform performance. Featuring Schmitt trigger inputs for high noise immunity and requiring only VDD bypass capacitors, they support data rates up to 150 Mbps with propagation delays under 10 ns. Enable inputs allow for single-point control of output drive, and selectable fail-safe modes control the default output state during power loss. Available with isolation ratings of 1.0, 2.5, 3.75, and 5 kV, and certified by UL, CSA, VDE, and CQC for ratings above 1 kV. Reinforced insulation up to 5 kVRMS is supported in wide-body packages. Automotive Grade is available for select part numbers, manufactured using automotive-specific processes for enhanced robustness and low defectivity.
