NOTES:
1. V
DD
must be raised to within the operating range before power down mode is exited.
2. Ports in quasi-bidirectional mode with weak pullup .
3. Ports in PUSH-PULL mode, both pullup and pulldown assumed to be the same strength.
4. In all output modes.
5. Port pins source a transition current when used in quasi-bidirectional mode and externally driven from 1 to 0. This current is highest when
V
is approximately 2V.
6. Measured with port in high impedance mode.
7. Measured with port in quasi-bidirectional mode.
8. Under steady state (non-transient) conditions, I
OL
must be externally limited as follows:
Maximum I

Maximum total I

If I
OL
exceeds the test condition, V
OL
may exceed the related specification. Pins are not guaranteed to sink current greater than the listed
test conditions.
