4. Capacitance loading on Ports 0 and 2 may cause spurious noise pulses to be superimposed on the V
OL
s of ALE and Ports 1
and 3. The noise is due to external bus capacitance discharging into the Port 0 and Port 2 pins when these pins make 1 to 0
transitions during bus operation. In the worst cases (capacitive loading 100pF), the noise pulse on the ALE line may exceed
0.45V with maxi V
OL
peak 0.6V. A Schmitt Trigger use is not necessary.
5. Typicals are based on a limited number of samples and are not guaranteed. The values listed are at room temperature and
5V.
6. 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 and 4 and 5 when available: 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 current greater
than the listed test conditions.
7. For other values, please contact your sales office.
