L Characteristics subject to change without notice ABSOLUTE MAXIMUM RATINGS (1) Parameters Ratings Units Temperature Under Bias –55 to +125 ºC Storage Temperature –65 to +150 ºC Voltage on any Pin with Respect to Ground (2) –2.0 to VCC + 2.0 V VCC with Respect to Ground –2.0 to 7.0 V Package Power Dissipation Capability (TA = 25°C) 1.0 W Lead Soldering Temperature (10 secs) 300 ºC Output Short Circuit Current (3) 100 mA D.C. OPERATING CHARACTERISTICS VCC = 2.7V to 5.5V and over the recommended temperature conditions unless otherwise specified.

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. (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 voltage on output pins is VCC +0.5V, which may overshoot to VCC +2.0V for periods of less than 20 ns. (3) Output shorted for no more than one second. No more than one output shorted at a time. (4) VIL min and VIH max are reference values only and are not tested. (5) This parameter is tested initially and after a design or process change that affects the parameter. Not 100% tested. |
