8.6.1 Device Address
Following a start condition, the bus master must output the address of the slave it is accessing. The address of the TCA9546A is shown in Figure 13. To conserve power, no internal pullup resistors are incorporated on the hardware-selectable address pins, and they must be pulled high or low.
Figure 13. TCA9546A Address The last bit of the slave address defines the operation to be performed. When set to a logic 1, a read is selected, while a logic 0 selects a write operation.
