ABSOLUTE MAXIMUM RATINGS

Temperature Under Bias ................. –55°C to +125°C

Storage Temperature ....................... –65°C to +150°C

Voltage on any Pin with

Respect to Ground(1) ............ –2.0V to +VCC +2.0V

VCC with Respect to Ground ............... –2.0V to +7.0V

Package Power Dissipation

Capability (TA = 25°C) ................................... 1.0W

Lead Soldering Temperature (10 secs) ............ 300°C

Output Short Circuit Current(2) ........................ 100 mA

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.

Note:

(1) 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.

(2) Output shorted for no more than one second. No more than

one output shorted at a time.

D.C. OPERATING CHARACTERISTICS

VCC = +3.0V to +5.5V and over the recommended temperature conditions unless otherwise specified.
