3 Description

The ISOW7741-Q1 and ISOW7742-Q1 devices are

galvanically-isolated quad-channel digital isolator with

an integrated high-efficiency power converter with low

emissions. The integrated DC-DC converter provides

up to 550 mW of isolated power, eliminating the

need for a separate isolated power supply in spaceconstrained

isolated designs.
