(1) VCCI is the VCC associated with the input port.
(2) VCCO is the VCC associated with the output port.
(3) For I/O ports, the parameter IOZ includes the input leakage current.
(4) All typical data is taken at 25°C.
(5) The bus-hold circuit can sink at least the minimum low sustaining current at VIL max. IBHL should be measured after lowering VIN to GND and then raising it to VIL max.
(6) 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.
(7) An external driver must source at least IBHLO to switch this node from low to high.
(8) An external driver must sink at least IBHHO to switch this node from high to low.
