ABSOLUTE MAXIMUM RATINGS
D.C. OPERATING CHARACTERISTICS
V
Notes:
(1) Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings
(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
(3) Output shorted for no more than one second. No more than one output shorted at a time.
(4) V
(5) This parameter is tested initially and after a design or process change that affects the parameter. Not 100% tested.
