*Comments
Stresses above those listed under "Absolute Maximum
Ratings" may cause permanent damage to this device.
These are stress ratings only. Functional operation of
this device at these or any other conditions above those
indicated in the operational sections of this specification
is not implied or intended. Exposure to the absolute
maximum rating conditions for extended periods may
affect device reliability.

Note 1: There are 2 types for DATA/CLK driving capability. The specification of VOH2 is the same as NT6868A. Under this
condition, user can select mask option 1 or 3 for this specification.
Note 2: The driving capability of DATA/CLK is higher than V OH2. Under this condition, a user can select mask option 5 or 7
for this specification.
