NTS0104 internal pull-up resistor, output voltage accuracy

1. Please tell me the tolerance of 10kΩ internal pull-up resistor of B port.

2. If the current source of B port is only 10kΩ internal pull-up resistor, which does output voltage tolerance depend on VCC or 0.67VCCO?

1:Tolerance is about +-20%

2: You can check datasheet page8 table9 for VOH/VOL specification.
