Tool/software:

Hi Team,

I would like to check what factors judge the VOH? (VCCB*0.67)

What condition would let VOH = VOH(mini) (0.67VCCB)?

According to the to the app note, it looks like that when T2 turn on, B port should be VCCB, not sure why VOH would become low. Feel free to let me know if I have any misunderstanding.

That value does not really make sense. The high voltage is generated by the pull-up resistor, so the voltage drop for a 20 µA current should be roughly 0.2 V.

This refers to what happen when an external pull down R =20k ohm is added?

I do not understand this question. The TXS does not work with a pull-down resistor.
