[1] V_CCO is the supply voltage associated with the output port.
[2] V_CCI is the supply voltage associated with the data input port.
[3] The bus hold circuit can sink at least the minimum low sustaining current at V_IL max. I_BHL should be measured after lowering V_I to GND
and then raising it to V_IL max.
[4] The bus hold circuit can source at least the minimum high sustaining current at V_IH min. I_BHH should be measured after raising V_I to V_CC
and then lowering it to V_IH min.
[5] An external driver must source at least I_BHLO to switch this node from LOW to HIGH.
[6] An external driver must sink at least I_BHHO to switch this node from HIGH to LOW.
[7] For I/O ports, the parameter I_OZ includes the input leakage current.
