SI8640ET-AS2R

Digital Isolators Overview

The SI8640ET-AS2R is a Skyworks Solutions automotive-grade digital isolator featuring four unidirectional channels in a 16-SOIC package. It utilizes capacitive coupling technology to provide 5000 Vrms isolation voltage with 10 kV surge capability. The device supports data rates up to 150 Mb/s with a propagation delay of 8 ns and pulse width distortion of 0.2 ns. Operating on a supply voltage range of 2.5 V to 5.5 V, it draws a typical operating current of 6.1 mA. Certified under AEC-Q100 standards, it functions reliably within a temperature range of -40°C to +125°C.
