Part Number: TCA9548A

Hi Sirs, 

From TCA9548A datasheet, it can be used in one master to 8 slaves. 

Can TCA9548A use in one slaves to 8 master? thanks.

    Hi Molly,

    Yes, this is OK. However, note that at start-up all of the channels are disabled. The device connected to the SDA and SCL lines needs to turn on any needed channels by writing to the TCA9548A's control register. This means that a master device would be required on the SDA/SCL side of the device. Please let me know if you have any questions.
