Hi,

Some comment below:

I recommend customer to use our latest TMUXHS4212
If this device is connected to a USB-C connector then TX1/2 should be AC coupled with 220nF and RX1/2 should be AC coupled with 330 nF. These values are highly recommended when AC coupling to a USB-C connector.
- If AC coupled at teh connector then AC coupling on A0 and A1 is not needed
Is OE being controlled?
Is PD/CC controller controlling the SEL pin?
