Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTES: 1. The input and output voltage ratings may be exceeded if the input and output current ratings are observed. 2. The package thermal impedance is calculated in accordance with JESD 51-7.

IO = 0 One input at 0.5 V or 2.4 V, Other inputs at 0 or VCC
This is the increase in supply current for each input that is at one of the specified TTL voltage levels, rather than 0 V or VCC.
