Notes:
(1) Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions outside of those listed in the operational sections of this
specification is not implied. Exposure to any absolute maximum rating for extended periods may affect device performance and reliability.
(2) This parameter is tested initially and after a design or process change that affects the parameter.
(3) Latch-up protection is provided for stresses up to 100mA on address and data pins from -1V to V_CC + 1V
(4) I_W = source or sink
