Part Number: PCA9543A

Dear SIR:

May I have some confirming item for  PCA9543A application ?

As we know that we have "Device 1 and Device 2  have the same SMBUS Address".

Therefore,We use PCA9543A  2-Channel I 2C Bus Switch  Device 1 and Device 2.

But we have confirming item as below:

If  we have 2  Daughter Board connect together by cable from Host (Detail as below)

Would you help to double confirming the PCA9543A application have any problem ?

(Ex: Daughter Board (1) Device 1  and  Daughter Board (2) Device 1  have any issue?(When Host side control it ) )

Thanks

    Hey TAlex,

    That shouldn't be a problem as long as the PCA9543A is a different address from the other. (Address on PCA9543A must be unique). The only other concern is to be sure you only enable one device/channel at a time so you can avoid address conflicts with device #1 and #2.

    Thanks,
