00 — Overview

What the Si8610 does

The Si861x/2x family comprises single and dual-channel digital isolators available in industrial and automotive grades. These CMOS devices support data rates up to 150 Mbps with propagation delays under 10 ns. They operate across a 2.5 V to 5.5 V supply range and offer isolation ratings from 2.5 kV to 5 kV RMS. Engineers typically use them in industrial automation, medical electronics, and electric vehicle applications. The parts feature Schmitt trigger inputs, selectable fail-safe modes, and wide temperature ranges from –40 to 125 °C. Options include SOIC-8 and wide-body SOIC-16 packages with reinforced insulation for safety-critical designs.
