ds26Lv31t: Combination of RS-422 Driver and Receiver

Part Number: ds26Lv31t

Dear Sirs,

My customer asked us about  combination of RS-422 Driver and Receiver.

They are using to combine as below.

1.DS26LV31T and DS26C32AT

2.DS26LV32AT and DS26C31T

 I checked datasheet .

DS26LVxx is 3.3V operation.

DS26Cxx is 5V operation.

Also there is description of Interoperable with Existing 5V RS-422 Networks.

So I think that there is no problem as the operation with the above combination.
Is this correct?

Please also let me know your attention points if possible.

Best Regards,
