SI86S640EC-AS1R

Overview

The SI86S640EC-AS1R is an automotive-grade digital isolator from Skyworks Solutions, featuring four unidirectional channels with capacitive coupling. It provides a 3.75 kVrms isolation voltage and supports data rates up to 150 Mbps. The device operates within a supply voltage range of 2.5 V to 5.5 V and functions across a temperature range of -40°C to +125°C. Packaged in a 16-pin SOIC-NB (0.154 inch width) reel, it ensures high common-mode transient immunity for reliable signal transmission in harsh automotive environments.
