This is the bus-hold maximum dynamic current required to switch the input from one state to another.
§Current into an output in the high state when VO > VCC
High-impedance state during power up/high-impedance state during power down
#This is the increase in supply current for each input that is at the specified TTL voltage level rather than VCC or GND.
