[1] All typical values are at Tamb = 25 C.

[2] Unused pins at VCC or GND.

[3] 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 s 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.
