† 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.
