NOTE :
1. The tolerance limits are specified after calibration with stable voltage and temperature. For the behavior of the tolerance limits if temperature or voltage changes after calibra-
tion, see following section on voltage and temperature sensitivity
2. The tolerance limits are specified under the condition that V_DDQ = V_DD and that V_SSQ = V_SS
3. Pull-down and pull-up output driver impedance are recommended to be calibrated at 0.5 X V_DDQ. Other calibration schemes may be used to achieve the linearity spec shown
above, e.g. calibration at 0.2 X V_DDQ and 0.8 X V_DDQ
4. Measurement definition for mismatch between pull-up and pull-down, MMpupd: Measure RONpu and RONpd. both at 0.5 X V_DDQ:
RONpu - RONpd
MMpupd =
