The max of 8 of these multiplexers can be connected together on 0x70-
0x77 addresses in order to control 64 of the same I2C addressed parts. By
connecting the three address bits A0, A1 and A2 to VIN it can get different
combination of the addresses. This is how an address byte of the
TCA9548A looks like. First 7-bits combine to form the slave address. The
last bit of the slave address defines the operation (read or write) to be
performed. When it is high (1), a read is selected, while a low (0) selects a
write operation.
NOTE:
The TCA9584A module can also act as logic level converter; i.e. all
I2C devices can have their own power supply/voltage. Further explanations
of this functionality is not in the scope of this eBook.
