RELIABILITY CHARACTERISTICS
Notes:
(1) Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings
(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 100 mA on address and data pins from -1V to V
