NOTES:
1. All typical values are at V

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

CC
= 3.3V
±

4. Unused pins at V
CC

5. I
CCZ
is measured with outputs pulled up to V
CC
or down to GND.
6. This is the bus hold overdrive current required to force the input to the opposite logic state.
