Current into device pins is defined as positive. Current out of device pins is defined as negative. Voltages are referenced to ground

except VOD,

ΔVOD, VTH and VTL which are differential voltages.

(3)

The VOD specification is a measurement of the difference between the single-ended VOH and VOL output voltages across a100 ohm

load. Applying the formula OUT+ - OUT- to the differential outputs will result in a waveform with peak to peak amplitude equal to twice

the datasheet indicated VOD.
