(1) VCCO is the VCC associated with the output port.
(2) VCCI is the VCC associated with the input port.
(3) The bus-hold circuit can sink at least the minimum low sustaining current at the VIL maximum. IBHL should be measured after lowering VIN to GND and then raising it to VIL maximum.
(4) The bus-hold circuit can source at least the minimum high sustaining current at VIH min. IBHH should be measured after raising VIN to VCC and then lowering it to VIH min.
(5) An external driver must source at least IBHLO to switch this node from low to high.
(6) An external driver must sink at least IBHHO to switch this node from high to low.
