(1) All typical values are at nominal supply voltage (2.5-, 3.3-, 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 (P7–P0) must be limited to a maximum current of 200 mA.

(4) RESET = V_CC (held high) when all other input voltages, V_I = GND.
