(1) Stresses beyond those listed under Absolute Maximum Rating may cause permanent damage to the device. These are stress
ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated
under Recommended Operating Condition. Exposure to absolute-maximum-rated conditions for extended periods may affect device
reliability.
(2) If the logic signal driving MR is less than V
DD
, then additional current flows into V
DD
and out of MR.
(3) The absolute maximum rating is (VDD + 0.3) V or 6.5 V, whichever is smaller
(4) As a result of the low dissipated power in this device, it is assumed that T
J
= T
