Hello,
Will it affect the result of the single-ended output (LVTTL) if I leave the low side of the RS-422 differential input unconnected (floating)?
The RS-422 line receiver that I use has the part number DS26LV32ATM.
Thanks for your help.

TK,
Is this still the case when only one of the inputs are left open?

Hi Reagan,
This part was designed for differential and not single-ended input operation. In which case would there only be one input left open?
Thanks,
Michael
Hi Reagan,
There is internal bias to support the open fail safe feature. One input pin is pulled a little positive than the other pin through internal biasing. This ensures logic high at output when both inputs are open.
If there is only one pin open, there is no guarantee the output will be at logic high.
