Hi Guowei,

Thanks a lot for your quick update.

PCA9509 should be the best option for our application.

By the way,  can you help to advise if any design consideration for the EN pin of PCA9509?

Can I just connect the EN pin to VCCA via a 10k resistor?

Or it also can be connected to VCCB?  

Regards

HI Boler

Connect the EN pin to VCCA via a 10k resistor should be OK.

Thanks!
