These devices isolate high-speed digital signals and offer performance, reliability, and flexibility advantages not available with optocoupler solutions. The Si871x/2x series is Patent pending based on Skyworks Solutions proprietary CMOS isolation technology for low- power and high-speed operation and are resistant to the wear-out effects found in optocouplers that degrade performance with increasing temperature, forward current, and device age. As a result, the Si871x/2x series offer longer service life and dramatically higher reliability compared to optocouplers. Ordering options include logic output with and without output enable options. Automotive Grade is available for certain part numbers. These products are built using automotive-specific flows at all steps in the manufacturing process to ensure the robustness and low defectivity required for automotive applications.
