5. The full variation in the ratio of the maximum to minimum pullup and pulldown current will not exceed 1.7, for device drain to source
voltage from 0 to VDDQ/2
6. The Full variation in the ratio of the nominal pullup to pulldown current should be unity ±10%, for device drain to source voltages
from 0 to VDDQ/2
