[1] All typical values are measured 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 ms is permitted. This parameter is valid for Tamb = +25 °C only.
[5] ICC with the outputs disabled 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.
