[SOLVED] RS422 line receiver ic selection

[little0192]

Hi,

I need to select a rs422 differential line receiver. So far i have selected the two Ic :

1. MAX3096

2. DS26LV31T

3. AMS26lv32
link - https://www.ti.com/lit/ds/symlink/am26lv32.pdf

priority
Performance -> features -> price

by looking at the switching characteristics DS26LV31T is the best followed up by AMS26lv32. Both are close in timing specifications. But if you see Timing characteristics they are like high as compared to above two IC's even though MAX3096 is double in the price.

Please let me know if i am missing on something here.
Right now my vote goes to DS26LV31T.

Also i think AMS26lv32 is newer so may be new improvements must be there.

I will be happy to see if someone sums up the details and help me choose the right IC.

Speed of the signal used in the project will be around 10-50kHz.

Thank You

Any RS-422 receiver on the market is good at least for several MHz, so all will fit.

You might be more interested in the "abnormal conditions"
(a prime reason for using RS-422 or RS-485 in the first
place) than the explicit paramtrics (other than power).
Standards are met, basically, on any of them. But for
example, some only hew to the open-input failsafe that
the spec calls out, while others also deal with shorted
input or one-input-open conditions more neatly; the
input ESD tolerance also has improved across the few
decades since I did RS-422 chip designs, and modern
consumer and industrial electronics people now will
demand more product-level ESD ruggedness just because
they can (forcing you to pick a part, to match).
