SI8631BT-AS2R

Digital Isolators Overview

The SI8631BT-AS2R is a Skyworks digital isolator featuring three channels with two unidirectional forward and one reverse path. It utilizes capacitive coupling technology to provide 5000 Vrms isolation voltage and supports data rates up to 150 Mb/s. The device operates within a supply voltage range of 2.5 V to 5.5 V, consuming 3.9 mA of typical operating current. It offers a propagation delay of 8 ns with rise and fall times of 4 ns each. Designed for automotive applications, it withstands 10 kV surge and functions reliably across an extended temperature range from -40°C to +125°C.
