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. Because the CPC5903 provides an isolated bidirectional buffer for the I2C data signal and a unidirectional buffer for the I2C clock signal, it is best suited for applications where clock stretching is not required. This configuration also requires the I2C bus master to be on the Side A bus. Unlike transformer or capacitive isolators, optical isolation passes DC signals and does not require continuous clocking to ensure the proper state is maintained. The CPC5903 always returns the buffered signals to their proper state after transient interruptions on either side.
