NVT2008 with pushpull outputs in both sides.

Hi!

I have an implmementation doubt in regard the usage of this chip.

I have to interfaces a 3.3v domain (microcontroller) witha 5V domain (lcd).

From both sides I have pushpull outputs and hiz inputs.

Do I need pullup resistos on both sides or all the examples from the datasheet are targeting to opendrain outputs?

Table 7, for example, shows minimum pullup resistor values. but in 7.4 "How to size pullup..." exlicits that it is for OD outputs. 

However, somewhere in the datasheet says that for PP outputs pull up resistors mey be required.

With which criteria?

thanks in advance.
