Sorry, that table was for the output levels, the table below is the one for the input levels.

Go back and read the first post; it explains that you can deal with positive going logic where the +ve rail is between 1.65 and 5.5V and there is a choice between 2 different voltage level translators which cover voltage ranges as follows.
1. 0.65V - 3.6V logic levels using a SN74AXC8T245 as U3 on the probe PCB
2. 1.6V - 5.5V logic levels using a SN74LVC8T245 as U3 on the probe PCB (and other minor component differences)
The definition of high and low on the inputs is purely a function of the voltage on VccA of the VLT IC, the setting on the scope can be ignored.

Hi, friends!
I'm create new topic with EasyEDA project low cost logic analyzer probe for Rigol MSO5000 here:
