For conditions shown as MIN or MAX, use the appropriate value specified under recommended operating conditions.
§Unused terminals at VCC or GND
This parameter is specified by characterization but is not production tested.
#This is the increase in supply current for each input that is at the specified TTL voltage level rather than VCC or GND.
