SI8641EB-AU

Digital Isolators Overview

The SI8641EB-AU is a Skyworks Solutions digital isolator featuring four unidirectional channels with three forward and one reverse configuration. It utilizes capacitive coupling technology to provide an insulation voltage of 2500 Vrms. The device supports data rates up to 150 Mb/s with a propagation delay of 8 ns. Operating on a supply voltage between 2.375 V and 5.5 V, it draws 6.6 mA of quiescent current. Packaged in a QSOP-16 format, it is AEC-Q100 qualified for automotive applications and functions within a temperature range of -40°C to +125°C.
