CPC5903 Datasheet (IXYS) - Optically Isolated I2C Bus Repeater

CPC5903, Optically Isolated I2C Bus Repeater

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
