The input levels and difference voltage provide no noise immunity and should be tested only in a static, noise-free environment.
This parameter is listed using a magnitude and polarity/direction convention, rather than an algebraic convention, to match the original
Agere data sheet.
Outputs of unused receivers assume a logic 1 level when the inputs are left open. (It is recomended that all unused positive inputs be
tied to the positive power supply. No external series resistor is required.)
Test must be performed one lead at a time to prevent damage to the device.
