Mikroe I2C Isolator 3 Click offers completely isolated bidirectional communication and features the IXYS CPC5902 dual optically isolated bidirectional logic-bus repeater. The CPC5902 pass DC signals and don’t need to be clocked periodically to sustain the logic states. It supports I2C clock stretching while providing 3750Vrms of galvanic isolation. The click can also function as a logic level translator for levels as low as 2.7V or as high as 5.5V when different supply voltages are applied on both power sides of the CPC5902.
