3 / 8 page 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 2) −0.5V to +7.0V Input Current (Note 2) −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 values beyond which the device may be damaged or have its useful life impaired. Functional operation under these conditions is not implied. Note 2: Either voltage limit or current limit is sufficient to protect inputs.
