1. Unused inputs must be held high or low to prevent them from floating.

2. DC input signal voltage specifies the allow able DC excursion of differential input.

4. Differential cross-point voltage is expected to track variations of VDD and is the voltage at w hich the differential signal must be changed.

3. Differential inputs signal voltages specifies the differential voltage [VTR-VCP] required for sw itching, w here VTR is the true input level and

VCP is the complimentary input level.
