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_IN 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_OL per port pin:
15mA (*NOTE: This is 85°C specification for V_DD = 5V.)
Maximum I_OL per 8-bit port:
26mA
Maximum total I_OL for all outputs:
71mA
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.
