Fig 25. Wiring transients limited by a Schottky diode
Question: If we add 100
smaller. Is this a good idea?
Answer: No, it is not necessary to add any resistance. When the logic signal generated
by TX or TY of PCA9600 drives long traces or wiring with ICs other than PCA9600
being driven, then adding a Schottky diode (BAT54A) as shown in
the wiring undershoot to a value that will not cause conduction of the IC’s internal
diodes.
