Hello,

I wanted to reach out to this wonderful community to seek some guidance regarding an issue I'm facing with the DS26LV32 and DS26LV31 ICs on my board. I believe your collective expertise and experience can help shed some light on this problem.

In my current project, I am utilizing the DS26LV31 IC for signal transmission and the DS26LV32 IC for signal reception. However, I've encountered an obstacle where the DS26LV32 IC does not generate the expected differential output.

I have checked the pcb connections from every end.

 

This is a pretty simple communication pair, and hard to get wrong.
Without a detailed Schematic of how You are using these matched-Chips,
it's hard to make even a guess at what might be creating a problem.

It might be as simple as a Pin-number mix-up, or excessive Output-Loading.

Show us a schematic diagram.
