The q denotes specifications which apply over the full operating
temperature range.
Note 1: Absolute Maximum Ratings are those values beyond which the life
of the device may be impaired.
Note 2: Timing for all input signals is measured at 0.8V for a High-to-Low
transition and at 2V for a Low-to-High transition.
Note 3: Timing specification are guaranteed but not tested.
Note 4: This is the minimum time required for valid data transfer.
