NOTES:
1. ``Typicals'' are based on a limited number of samples taken from early manufacturing lots and are not guaranteed. The
values listed are at room temp, 5V.
2. Capacitive loading on Ports 0 and 2 may cause noise pulses above 0.4V to be superimposed on the V
Ports 1, 2 and 3. The noise is due to external bus capacitance discharging into the Port 0 and Port 2 pins when these pins
change from 1 to 0. In applications where capacitive loading exceeds 100 pF, the noise pulses on these signals may exceed
0.8V. It may be desirable to qualify ALE or other signals with a Schmitt Trigger, or CMOS-level input logic.
3. Capacitive loading on Ports 0 and 2 may cause the V
cation when the address bits are stabilizing.
