PCA9548A I2C address confirm

Other Parts Discussed in Thread: PCA9548A

Hi Sirs, 

Sorry to bother you.

As title, My question as below

If we to series connection PCA9548A, The IC (A) and IC (X) are same I2C address(0XEA)

Have any risk to use same I2C address between IC (A) and (C)??

If Yes, could you share how to fix it??

Thanks for your reply

  • Hello Shu-Cheng,

    The PCA9548A has three address pins on depending on how you configure each of the PCA9548A address pins you can have up to 8 address, just assign one unique address per device.  The address pins are inputs that are either tied to ground or Vcc depending on desired logic.
