NOTES:
1. Capacitive loading on Ports 0 and 2 may cause noise pulses above 0.4V to be superimposed on the V
OL
s of ALE and
Ports 1, 2 and 3. The noise is due to external bus capacitance discharging into the Port 0 and Port 2 pins when these pins
change from 1 to 0. In applications where capacitance loading exceeds 100 pF, the noise pulses on these signals may
exceed 0.8V. It may be desirable to qualify ALE or other signals with a Schmitt Trigger, or CMOS-level input logic.
2. Capacitive loading on Ports 0 and 2 cause the V
OH
on ALE and PSEN to drop below the 0.9 V
CC
specification when the
address lines are stabilizing.
3. See Figures 6–9 for test conditions. Minimum V
CC
for power down is 2V.
4. Typicals are based on limited number of samples, and are not guaranteed. The values listed are at room temperature and 5V.
5. 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, and 3:
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.
