Preliminary Information
Stresses above those listed under “Absolute Maximum Ratings” may
causepermanentdamagetothedevice. Thesearestressratingsonly,
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.
ABSOLUTE MAXIMUM RATINGS

Note:
Respect to Ground(1) ............ –2.0V to +VCC +2.0V
(1) The minimum DC input voltage is –0.5V. During transitions,
inputs may undershoot to
VCC with Respect to Ground ............... –2.0V to +7.0V
–2.0V for periods of less than 20 ns. Maximum DC voltage on
output pins is V +0.5V, which may overshoot to V +2.0V
for periods of less than 20 ns.
(2) Output shorted for no more than one second. No more than
one output shorted at a time.
