  10. 10. Absolute Maximum Ratings (Note) If Military/Aerospace specified devices are required, please contact the National Semiconductor Sales Office/Distributors for availability and specifications. Supply Voltage 7V Input Voltage 7V Operating Free Air Temperature Range DM54LS and 54LS -55 °C to a125 °C DM74LS 0 °C to a70 °C Storage Temperature Range -65 °C to a150 °C Note: The ``Absolute Maximum Ratings'' are those values beyond which the safety of the device cannot be guaranteed. The device should not be operated at these limits. The parametric values defined in the `` Electrical Characteristics'’ table are not guaranteed at the absolute maximum ratings. The `` Recommended Operating Conditions'' table will define the conditions for actual device operation. © 2011 ESA Lab. ITIS GALILEO FERRARIS Verona (ITALY) / by Prof. Athos ARZENTON
