The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction
temperatures which are detrimental to reliability.

This is the bus hold overdrive current required to force the input to the opposite logic state.
[4]
This parameter is valid for any VCC between 0 V and 1.2 V with a transition time of up to 10 ms. From VCC = 1.2 V to VCC = 3.3 V ± 0.3 V
a transition time of 100 µs is permitted. This parameter is valid for Tamb = 25 °C only.
[5]
ICC is measured with outputs pulled to VCC or GND.
[6]
This is the increase in supply current for each input at the specified voltage level other than VCC or GND.
