Description for the ISOW7741

The ISOW7741 device is a galvanically-isolated quad-channel digital isolator with an integrated high-efficiency power converter with low emissions. The integrated DC-DC converter provides up to 500 mW of isolated power, eliminating the need for a separate isolated power supply in space-constrained isolated designs.
