Typical ratings are not guaranteed. The values listed are at room temperature (+25 ˚C), 5 V, unless otherwise stated.
Capacitive loading on ports 0 and 2 may cause spurious noise to be superimposed on the V
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 the worst cases (capacitive loading >100 pF), the noise pulse on the ALE pin may exceed 0.8 V. In such cases, it may be
desirable to qualify ALE with a Schmitt Trigger, or use an address latch with a Schmitt Trigger STROBE input. I

Capacitive loading on ports 0 and 2 may cause the V

Pins of ports 1, 2, 3 and 4 source a transition current when they are being externally driven from 1 to 0. The transition current reaches its
