(see Figure 23.).
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 100pF), the noise pulse on the ALE line may exceed 0.45V with maxi V
OL
peak 0.6V. A Schmitt Trigger use is not necessary.
5.
Typicals are based on a limited number of samples and are not guaranteed. The values listed are at room temperature and 5V.
6.
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, 3 and 4 and 5 when available: 15 mA
Maximum total I
OL
for all output pins: 71 mA
