NOTES:
1. Ports in Quasi bi-directional mode with weak pull-up (applies to ALE, PSEN only during RESET).
2. Ports in Push-Pull mode, both pull-up and pull-down assumed to be same strength
3. In all output modes
4. 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.
5. Measured with port in high impedance output mode.
6. Measured with port in quasi-bidirectional output mode.
7. Load capacitance for all outputs=80pF.
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

Maximum I
OL
per 8-bit port:

Maximum total I
for all output: 71mA
If I
exceeds the test condition, V
OL
may exceed the related specification. Pins are not guaranteed to sink current greater than the listed
test conditions.
