if the DDC channel of TPD7S019 is not used, as shown below,
1. Does Pin 7 VCC_DDC need to be connected to 3.3V?
2. Do any processing need to be done on Pin 9, Pin10, Pin11, and Pin12?

Hi Gareth,
1. VCC_DCC is an isolated supply input for the DDC_1 and DDC_2 level-shifting N-FET gates, so if DCC is not going to be used, VCC_DCC should be GNDed.
2. If unused, those pins can be left floating or GNDed with a pull down.
