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 space-constrained isolated designs.
