Note 2: âAbsolute Maximum Ratingsâ are those values beyond which the
safety of the device cannot be guaranteed. They are not meant to imply that
the devices should be operated at these limits. The table of âElectrical
Characteristicsâ specifies conditions of device operation.
Note 3: Absolute voltages referenced to VSS1 = VSS2 = 0.0V.

Note 5: VCMRSDS = (VCLKP + VCLKN)/2 or (VDxxP + VDxxN)/2.
Note 6: Positive means that DxxP (or CLKP) is higher than RSDS ground DxxN (or CLKN). Negative means that DxxP (or CLKP) is lower than RSDS ground DxxN
(or CLKN).
