Absolute Maximum Ratings(Note 1) If Military/Aerospace specified devices are required, please contact the National Semiconductor Sales Office/ Distributors for availability and specifications. Storage Temperature −65˚C to +150˚C Ambient Temperature under Bias −55˚C to +125˚C Junction Temperature under Bias Ceramic −55˚C to +175˚C V CC Pin Potential to Ground Pin −0.5V to +7.0V Input Voltage (Note 1) −0.5V to +7.0V Input Current (Note 1) −30 mA to +5.0 mA Voltage Applied to Any Output in the Disabled or Power-off State −0.5V to 5.5V in the HIGH State −0.5V to V CC Current Applied to Output in LOW State (Max) twice the rated I OL (mA) Recommended Operating Conditions Free Air Ambient Temperature Military −55˚C to +125˚C Supply Voltage Military +4.5V to +5.5V Note 1:Absolute maximum ratings are those values beyond which damage to the device may occur. The databook specifications should be met, without exception, to ensure that the system design is reliable over its power supply, temperature, and output/input loading variables. National does not recom- mend operation of FACT ® circuits outside databook specifications.
