Differential inputs signal voltages specifies the differential voltage [VT-VCP] required f or switching,
where VTR is the true input level and VCP is the complementary input level.
Differential cross-point voltage is expected to track variations of VDD and is the voltage at which the
differen tial signal must be crossing.

Unused inputs must be held high or low to prevent them from floating.
DC input signal voltage specifies the allowable DC excursion of differential input.
