† _{All typical values are at TA = 25°C.}
‡ _{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.
§ _{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.
¶ _{An external driver must source at least IBHLO to switch this node from low to high.}
# _{An external driver must sink at least IBHHO to switch this node from high to low.}
|| _{For I/O ports, the parameter IOZ includes the input leakage current.}
NOTES: 7. VCCO is the VCC associated with the output port.
8. VCCI is the VCC associated with the input port.
