[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 V
CC
between 0 V and 1.2 V with a transition time of up to 10 ms. From V
CC
= 1.2 V to V
CC
= 3.3 V ± 0.3 V a transition time
of 100 ms is permitted. This parameter is valid for T

[5] I
CC
with the outputs disabled is measured with outputs pulled to V
CC
or GND.
[6] This is the increase in supply current for each input at the specified voltage level other than V
CC
or GND.
