[1] For valid test results, data must not be loaded into the flip-flops (or latches) after applying the power.
[2] This parameter is valid for any VCC between 0 V and 2.1 V with a transition time of up to 10 ms. For VCC = 2.1 V to VCC = 5 V 10 %, a
transition time of up to 100 s is permitted.
[3] Not more than one output should be tested at a time, and the duration of the test should not exceed one second.
[4] This is the increase in supply current for each input at 3.4 V.
