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.
