[1] All typical values are measured at VCC = 3.3 V (unless stated otherwise) and Tamb = 25 °C.
[2] Unused pins at VCC or GND.
[3] 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 = 3.0 V to 3.6 V a transition time
of 100 ms is permitted. This parameter is valid for Tamb = +25 °C only.
[4] This is the bus hold overdrive current required to force the input to the opposite logic state.
[5] This is the increase in supply current for each input at the specified voltage level other than VCC or GND.
