All typical values are at nominal supply voltage (2.5-, 3.3-, or 5-V VCC) and TA = 25°C.
The total current sourced by all I/Os must be limited to 85 mA.
Each I/O must be externally limited to a maximum of 25 mA, and the P port (P7–P0) must be limited to a maximum current of 200 mA.
RESET = VCC (held high) when all other input voltages, VI = GND.
