‡
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 I
OZ
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 V
CC
or GND.
