† All typical values are at VCC = 3.3 V, TA = 25°C.

‡ For I/O ports, the parameter II includes the off-state output leakage current.

§ The bus-hold circuit can sink at least the minimum low sustaining current at VILmax. IBHL should be measured after lowering VIN to GND and

then raising it to VILmax.

¶ The bus-hold circuit can source at least the minimum high sustaining current at VIHmin. IBHH should be measured after raising VIN to VCC and

then lowering it to VIHmin.

# 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.

k This is the increase in supply current for each input that is at the specified TTL voltage level, rather than V

CC or GND.
