SI8663EC-AS1

Digital Isolators Overview

The SI8663EC-AS1 is a Skyworks Solutions automotive-grade digital isolator featuring six channels with three forward and three reverse directions. It utilizes capacitive coupling technology to provide galvanic isolation with an insulation voltage of 3750 Vrms. The device supports data rates up to 150 Mb/s and operates within a supply voltage range of 2.375 V to 5.5 V. Key electrical parameters include a propagation delay of 8 ns, rise and fall times of 4 ns, and a pulse width distortion of 0.2 ns. It functions reliably across temperatures from -40°C to +125°C in a SOIC-16 package.
