NOTES:
1. Not more than one output should be tested at a time, and the duration of the test should not exceed one second.
2. This is the increase in supply current for each input at 3.4V.
3. This parameter is valid for any V
CC
between 0V and 2.1V, with a transition time of up to 10msec. From V
CC
= 2.1V to V
CC
= 5
±
10% a
transition time of up to 100

sec is permitted.
4. This is the bus hold overdrive current required to force the input to the opposite logic state.
