Other Parts Discussed in Thread: SN65HVD3085E,
Hello Experts,
My customer is facing a communication error. Customer is connecting between SN65LBC184 and SN65HVD3085E. He mentioned that communication error occurred if termination resisters mounted. Would you please check the schematic and the waveform? If you find something, please let me know how to resolve this error. Also the external failsafe circuit is required at SN65LBC184 A/B-pins? It seems that this phenomenon occurred after SN65LBC184 DE goes High to Low transition. (I think SN65LVC184 A/B-pins went Hi-Z.)
