Notes:
(1) Stresses above those listed under âAbsolute Maximum Ratingsâ 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) The minimum DC input voltage is â0.5V. During transitions, inputs may undershoot to â2.0V for periods of less than 20ns. Maximum DC
voltage on output pins is VCC +0.5V, which may overshoot to VCC +2.0V for periods of less than 20 ns.
(3) Output shorted for no more than one second. No more than one output shorted at a time.
(4) This parameter is tested initially and after a design or process change that affects the parameter.
(5) Latch-up protection is provided for stresses up to 100 mA on address and data pins from â1V to VCC +1V.
