It galvanically isolates two open-drain logic signals, and provides a galvanic isolation of 3750Vrms. When the two sides’ supply voltages are configured with different voltages, the CPC5902 also functions as a logic level translator for levels as low as 2.7V or as high as 5.5V. Unlike transformer or capacitive isolators, the optically isolated repeaters pass DC signals, and do not need to be clocked periodically to sustain the logic states. Buffered signals will always return to their proper value after a transient interrupt...
