NOTES:
1. Typical ratings are not guaranteed. The values listed are at room temperature, 5V.
2. Capacitive loading on ports 0 and 2 may cause spurious noise to be superimposed on the V
3. Capacitive loading on ports 0 and 2 may cause the V
4. 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
5. See Figures 22 through 25 for I
6. This value applies to T
7. Load capacitance for port 0, ALE, and PSEN = 100pF, load capacitance for all other outputs = 80pF.
8. Under steady state (non-transient) conditions, I
9. ALE is tested to V
10. Pin capacitance is characterized but not tested. Pin capacitance is less than 25pF. Pin capacitance of ceramic package is less than 15pF

worst cases (capacitive loading > 100pF), the noise pulse on the ALE pin may exceed 0.8V. 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
