Notes:
1. Unused inputs must be held high or low to prevent them from floating.
2. DC input signal voltage specifies the allowable DC execution of differential input.
3. Differential inputs signal voltages specifies the differential voltage [VTR-VCP] required for switching, where
VTR is the true input level and VCP is the complementary input level.
4. Differential cross-point voltage is expected to track variations of V_DDQ and is the voltage at which the
differential signal must be crossing.
