(1)
All typical values are at VCC = 3.3 V, TA = 25°C.
(2)
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.
(3)
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.
(4)
An external driver must source at least IBHLO to switch this node from low to high.
(5)
An external driver must sink at least IBHHO to switch this node from high to low.
(6)
For I/O ports, the parameter IOZ includes the input leakage current.
