The difference between SN74LVCH162244A and SN74LVC162244A  is the "H" one has input bus hold.

What is the implemnetation for this one. It is held always to "H", to "L" or previous value?

If always H or L, what is the pull up and pull down resistance range internally?

I got the current rating for the bus hold circuitry. So for SN74LVC162244A (no bus hold), what is the worst effect on the output if the input is float?
