For SN74LVCH162244, the bus hold part, on data sheet page 4, there is Ihold with note (3)
This is the bus-hold maximum dynamic current. It is the minimum overdrive current required to switch the input from one state to another.
My question is that current 500uA is for one input or all inputs total at the same time to switch to another logic. How about 75uA above, the minimum per inputs or total inputs at 3V power voltage?
