TPD7S019: spec check

Part Number: TPD7S019

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.

    BR,
