(1) The bus-hold circuit can sink at least the minimum low sustaining current at V_IL maximum. I_BHL should be measured after lowering V_IN to GND and then raising it to V_IL maximum.

(2) The bus-hold circuit can source at least the minimum high sustaining current at V_IH mininum. I_BHH should be measured after raising V_IN to V_CC and then lowering it to V_IH minimum.

(3) An external driver must source at least I_BHLO to switch this node from low to high.

(4) An external driver must sink at least I_BHHO to switch this node from high to low.

(5) V_CCO is the voltage associated with the output port supply VCCA or VCCB.

(6) V_CCI is the voltage associated with the input port supply VCCA or VCCB.

(7) V_OH: Output High Voltage; V_OL: Output Low Voltage; I_I: Control Input Current.

(8) I_off: Partial Power Down Output current; I_OZ: Hi-Z Output Current; I_CCA: Supply A Current; I_CCB: Supply B Current.
