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 VT is the true input level and VCP is the
complementary input level.
4. Differential cross-point voltage is expected to track variations of VCC and is the
voltage at which the differential signal must be crossing.
