1. Under steady state (non-transient) conditions, I
OL
must be externally limited as follows:
Maximum I
OL
per port pin: 15mA
Maximum I
OL
per 8-bit port: 26mA
Maximum I
OL
total 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.
2. Capacitive loading on Ports 0 and 2 may cause spurious noise to be superimposed on the V
OL
s of ALE and Ports 1 and 3. The noise
due to external bus capacitance discharging into the Port 0 and 2 pins when the pins make 1-to-0 transitions during bus operations.
In the worst cases (capacitive loading > 100pF), the noise pulse on the ALE pin may exceed 0.8V. In such cases, it may be desirable
to qualify ALE with a Schmitt Trigger, or use an address latch with a Schmitt Trigger STROBE input.
3. Load capacitance for Port 0, ALE and PSEN#= 100pF, load capacitance for all other outputs = 80pF.

4. Capacitive loading on Ports 0 and 2 may cause the V
OH
on ALE and PSEN# to momentarily fall below the V
DD
- 0.7 specification
when the address bits are stabilizing.
5. Pins of Ports 1, 2, and 3 source a transition current when they are being externally driven from 1 to 0. The transition current reaches
its maximum value when V
IN
is approximately 2V.
6. Pin capacitance is characterized but not tested. EA# is 25pF (max).
