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 capacitive 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 Triggers, 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 a 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:
10mA
Maximum I
OL
per 8-bit portD
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.
