(see Fig-
ure 5).
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 100 pF), the noise pulse on the ALE line may exceed
0.45V with maxi V
OL
peak 0.6V. The use of a Schmitt Trigger is not necessary.
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
