(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) Each I/O must be externally limited to a maximum of 25 mA, 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.
(3) 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).
