The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings. The “Recommended Operating Conditions” table will define the conditions for actual device operation. Recommended Operating Conditions Electrical Characteristics over recommended operating free air temperature range (unless otherwise noted) Switching Characteristics at VCC = 5V and TA = 25°C (See Section 1 for Test Waveforms and Output Load) Note 2: All typicals are at VCC = 5V, TA = 25°C. Note 3: Not more than one output should be shorted at a time and the duration should not exceed one second.
