CPC5903G Description

The CPC5903 is a dual, optically isolated, logic-bus repeater. It isolates two open-drain logic signals while providing 3750Vrms of galvanic isolation. When the two sides are powered by different supply voltages, it also functions as a logic level translator for levels as low as 2.7V or as high as 5.5V.
