(1) V_CCO is the V_CC associated with the output port.
(2) V_CCI is the V_CC associated with the 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_IN 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_IN 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.
