Dear engineer of NXP,
I am doing failure analyse, because the can transeiver PCA82C50 can't communicate normaly.
What will happen, if the input current through TXD/RXD is larger than the max limited current , when I connect a small resistance between 5V supply and pin TXD/RXD. Will it lead to communication failure , or IC damage？(Figure1)
Thus,
- I need to know what limited current(min., max., typ.) of pin RXD , TXD, just like TJA1044 datasheet's decription(Figure2).
- It is beterr if there is a pin FMEA description document about PCA82C50 .(Figure3)
But I can't find any one just like above two point from datasheet or application hints about PCA82C250.
