(1) All typical values are at nominal supply voltage (2.5-V, 3.3-V, or 5-V V_CC) and T_A = 25°C.
(2) The total current sourced by all I/Os must be limited to 85 mA.
(3) Each I/O must be externally limited to a maximum of 25 mA, and the P port (P0 to P7) must be limited to a maximum current of 200 mA.
