NOTES

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 operations In applications where capacitance loading exceeds 100 pFs the noise pulse on the ALE

signal may exceed 08V In these cases it may be desirable to qualify ALE with a Schmitt Trigger or use an Address Latch

with a Schmitt Trigger Strobe input

address lines are stabilizing
