LVDS050 TTL to LVDS buffer -what to do with unused receiver inputs/outputs

Hi,

I am using the LVDS050 part in multiple places in my design. On one part I am not using the LVDS to LVTTL receiver. I have pulled the receiver enable to high to disable the receiver, but was wondering if I need to do anything to the LVDS inputs or LVTTL output or just leave them disconnected.

Thanks!

  • Hi,

    see "10.3.5.2 Receiver Open-Circuit Fail-Safe" in datasheet.

    Leave them disconnected seems good to me :) But you may prefer resistor at the input and/or output just in case it might become usefull later in your projet (better choice if not space challenged).

    Have a good day,
