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,

Y.Hasebe

Hello Hasebe-san,

Yes, it is OK to mix devices powered by 5 V and powered by 3.3 V on a shared network. The important thing is that all devices conform to the given standard, in this case RS-422. The devices you have mentioned above will communicate with one another without issue.

Regards,
Max
