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 VD D and is the voltage at which the

differential signal must be crossing.

Differential input signal

voltage (note 3)

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.
