(1)

All typical values are at nominal supply voltage (2.5-V, 3.3-V, or 5-V VCC) and TA = 25°C.

(2)

The total current sourced by all I/Os must be limited to 85 mA.

(3)

Each I/O must be limited externally to a maximum of 25 mA, and the P-port (P3–P0) must be limited to a maximum current of 100 mA.
