SI86S631BE-AS2

Digital Isolators Overview

The SI86S631BE-AS2 is an automotive-grade digital isolator from the Si86SM4x series, manufactured by Skyworks Solutions. It features three unidirectional channels with a 6.0 kVrms isolation rating and capacitive coupling technology. The device operates within a supply voltage range of 2.5 V to 5.5 V and supports data rates up to 150 Mb/s. Key electrical parameters include a propagation delay of 8 ns, rise/fall times of 4 ns, and a typical operating current of 3.9 mA. It is housed in a 16-pin SOIC-WB package and functions without a shutdown pin.
