TCA9548A: Who gives the ACK signal when all channels are activated at the same time?

The TCA9548A is a passive switch; all enabled channels are directly connected together.

It is not allowed to access multple devices with the same address. When you do have multple devices with the same address, then you must enable only one channel at the same time.

Hello Yun,

I agree with Clemens answer, but  if you have nay further questions please let us know!

Thank you for your response.

I've noticed that I've been using it wrong so far.

It seemed to work, but it wasn't the right way to use it.

If you have multiple devices with the same address, we will enable only one channel.
