Note:
1. Under steady state (non-transient) conditions, I
OL
must be externally limited as follows:
Maximum I
OL
per port pin: 10 mA
Maximum I
OL
per 8-bit port
Port 0: 26 mA
Ports 1, 2, 3: 15 mA
Maximum total I
OL
for all output pins: 71 mA
If I
OL
exceeds the test condition, V
OL
may exceed the related specification.
Pins are not guaranteed to sink greater than the listed test conditions.
