Preliminary Information
ABSOLUTE MAXIMUM RATINGS
Lead Soldering Temperature (10 secs) ............ 300°C
Output Short Circuit Current(2) ........................ 100 mA
Temperature Under Bias ................. –55°C to +125°C
Storage Temperature....................... –65°C to +150°C
Stressesabovethoselistedunder“AbsoluteMaximumRatings”maycausepermanentdamage
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.
Voltage on any Pin with
Respect to Ground(1) ............ –2.0V to +VCC +2.0V
Note:
(1) The minimum DC input voltage is –0.5V. During transitions, inputs may undershoot to
V
CC 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
CC
+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
