NOTES:
1. All typical values are at V
CC
= 2.5V and T
amb
= 25°C.
2. This is the increase in supply current for each input at the specified voltage level other than V
CC
or GND
3. This parameter is valid for any V
CC
between 0V and 1.2V with a transition time of up to 10msec. From V
CC
= 1.2V to V
CC
= 2.5V ± 0.2V a
transition time of 100µsec is permitted. This parameter is valid for T
amb
= 25°C only.
4. Unused pins at V
CC
or GND.
5. I
CCZ
is measured with outputs pulled up to V
CC
or pulled down to ground.
6. Not guaranteed.
