Test Conditions
NOTES:
1.
Under steady-state (non-transient) conditions, I
OL
must be externally limited as follows:
Maximum I
OL
per port pin: 10 mA
Maximum I
per 8-bit port:
port 0
26 mA
ports 1–3
15 mA
Maximum Total I
OL
for
all output pins
71 mA
If I
exceeds the test conditions, V
may exceed the related specification. Pins are not guaranteed
to sink current greater than the listed test conditions.
Capacitive loading on ports 0 and 2 may cause spurious noise pulses above 0.4 V on the low-level
outputs 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 high to low. In applications where capacitive
loading exceeds 100 pF, the noise pulses on these signals may exceed 0.8 V. It may be desirable to
qualify ALE or other signals with a Schmitt trigger or CMOS-level input logic.
Capacitive loading on ports 0 and 2 causes the V
OH
on ALE and PSEN# to drop below the specifica-
tion when the address lines are stabilizing.
Typical values are obtained using V
CC
= 5.0, T
A
= 25°C and are not guaranteed.
