It has a voltage divider (two resistors) to translate the 5v to 3v so this part is very easy to work with (RXhv=input, RXlv=output),.

In the reverse direction you need to connect the HV to 5v and LV to 3.3v power supply,
these two supply a mosfet so that you can get 5v from 3v3 (TXlv=input, TXhv=output)
