SI86SQ44BE-IS2R

Digital Isolators Overview

The Skyworks SI86SQ44BE-IS2R is a digital isolator featuring four reversible channels with a data rate of 150 Mbps. It provides an insulation voltage of 6.0 kVrms and supports a common-mode transient immunity (CMTI) of 100 kV/µs. The device operates within a supply voltage range of 2.5 V to 5.5 V and functions at temperatures from -40 °C to +125 °C. It utilizes capacitive coupling isolation technology and is housed in a 16-SOIC package.
