AUTOMOTIVE 87C51FAFBFCFC-20

NOTES

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

08V It may be desirable to qualify ALE or other signals with Schmitt triggers or CMOS-level input logic

address lines are stabilizing

4 Typicals are based on limited number of samples and are not guaranteed The values listed are at room temperature and
