RxDx pull-up resistor

The receive data outputs RxD1/RxD2 provide open drain behavior for allowing the output level to be adapted

to the microcontroller supply voltage. Because of this, 3.3 V microcontroller derivatives without 5 V tolerant

ports can be used. In case the microcontroller port pin does not provide integrated pull-up circuits, external

Figure 16 shows typical RxD1/RxD2 pin input current and input voltage characteristics across temperature.

The RxDx pull-up resistors can be dimensioned according to the minimum “high”-level input voltage and the

maximum “low”-level input voltage of the application’s microcontroller port pins’ (Rx). Typically pull-up
