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
or GND
3. This parameter is valid for any V
between 0V and 1.2V with a transition time of up to 10msec. From V

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