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 2 pins when the 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.
Load capacitance for Port 0, ALE and PSEN = 100 pF, load capacitance for all other outputs = 80 pF.
Capacitive loading on Ports 0 and 2 may cause the V

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