Fig 24. 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 P82B96 drives long traces or wiring with ICs other than P82B96 being
driven, then adding a Schottky diode (BAT54A) as shown in
wiring undershoot to a value that will not cause conduction of the IC’s internal diodes.
