Notes:
1 Unused inputs must be held high or low to prevent them from floating.
2 DC input signal voltage specifies the allowable DC excursion of differential input.
3 Differential inputs signal voltages specifies the differential voltage [VT-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 VD D and is the voltage at which the
differential signal must be crossing.
