The ISO7240CDWR is a digital isolator designed to transmit digital signals across an electrical isolation barrier. It works by converting electrical signals from the primary side (input) into optical signals and back to electrical signals on the secondary side (output). This isolation helps protect sensitive circuits from voltage spikes, noise, and other forms of electrical interference.
