All typical values are at nominal supply voltage (1.8 V, 2.5 V, or 3.3 V, VCC) and TA = 25°C.
Each I/O must be externally limited to the maximum allowed IOL, and each octal (P07–P00 and P17–P10) must be limited to a maximum current of 100 mA, for a device total of 200 mA at Tj ≤ 85°C. See the Section 6.3 table for more information.
The total current sourced by all I/Os must be limited to 160 mA (80 mA for P07–P00 and 80 mA for P17–P10) for Tj ≤ 85°C. See the Section 6.3 table for more information.
