[1] Unused inputs must be held HIGH or LOW to prevent them from floating.
[2] V_ref is normally ²â„₃V_TT, but based upon application and noise margin requirements can be set anywhere
within this range and does not need to follow GTL-/GTL/GTL+ specification.
[3] Nominally ±50 mV around V_ref. See Figure 4, Figure 5, and Figure 6 for actual performance versus V_ref,
V_CC, and temperature.
