*COMMENT
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 specifica-
tion is not implied. Exposure to any absolute maximum
rating for extended periods may affect device perfor-
mance and reliability.

Note:
(1) V_ILC = –0.3V to +0.3V.
(2) V_IHC = V_CC –0.3V to V_CC +0.3V.
(3) 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 V_CC +0.5V, which may overshoot to V_CC +2.0V for periods of less than 20 ns.
(4) Output shorted for no more than one second. No more than one output shorted at a time.
