[1] 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 µs is permitted.
[2] Not more than one output should be tested at a time, and the duration of the test should not exceed one second.
[3] This is the increase in supply current for each input at 3.4 V.
