(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 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.
