XinaBox xCHIP I2C Multiplexer Module AI01

This xChip is an interface module, based on the PCA9548A by NXP Semiconductors, which enables users to add more than one xChip with the same physical I²C address to a circuit. The PCA9548A operates as an I²C channel selector, this functionality is what enables communication with multiple I²C devices that have the same address. The channel selector ability is achieved through an octal bidirectional translating switch controlled by the I²C-bus.
