THVD1452: Inconsistency in documentation

Part Number: THVD1452

I am verifying the pinout of the THVD1452 and in the user guide for the evalutation guide it shows the following image (www.ti.com/.../RS485-FL-DPLX-EVM)

 

 Seeing that the Y terminal ins negative on the THVD1452 in the user guide of the eval kit made me confused and wanted to verify in the data sheet which shows the picture what I want (see below), but does not specify in the datasheet that the Y terminal is either positive or negatve (see picture below.

Can I get clarification that the Y terminal is either positive or the negative output of the THVD1452
