C.
This is the bus-hold maximum dynamic current. It is the minimum overdrive current required to switch the input from one state to another.
§For I/O ports, the parameter IOZ includes the input leakage current.
This is the increase in supply current for each input that is at the specified TTL voltage level rather than VCC or GND.
