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) The minimum DC input voltage is –0.5V. During transitions, inputs may undershoot to –2.0V for periods of less than 20 ns. 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) VIL min and VIH max are reference values only and are not tested.  
(5) This parameter is tested initially and after a design or process change that affects the parameter. Not 100% tested.
