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. NOTE 1: The input and output voltage ratings may be exceeded if the input and output current ratings are observed.

One input at 3.4 V, Other inputs at GND or VCC
Ci VI = VCC or GND 5V 3.5 Not more than one output should be tested at a time, and the duration of the test should not exceed 10 ms. § 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.
