I am using GTL2014 in our design and the Direction pin been set to High (1K pu to 3.3V) ie LVTTL to GTL translation. Currently I have set the VREF to 2/3 of VTT. I would like to know, whether VREF has any importance during LVTTL to GTL translation? as VREF is used as a threshold reference during GTL to LVTTL translation.
Please let me know the consequences of setting VREF to 2/3 VTT in such scenario (DIR= H).
