NOTES:
1. Capacitive loading on Ports 0 and 2 may cause 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 operations. In applications where capacitance loading exceeds 100 pFs, the noise pulse on the ALE
signal may exceed 0.8V. In these cases, it may be desirable to qualify ALE with a Schmitt Trigger, or use an Address Latch
with a Schmitt Trigger Strobe input.
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 2.0V.
4. Typicals are based on limited number of samples, and are not guaranteed. The values listed are at room temperature and
5.0V.
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
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.
6. Contact Intel for design-in information.
