HummingBoard Ripple v2.5 schematics has U25 which is IC buffer NLX2G16AMUTCG between UART2 TX/RX pins and FT230X TXD RXD pins. Am I right that only reason for this IC is to amplify weak electrical signal? There is no logic level shifting or inverting there?

And should I add similar IC buffer on my own design for i.MX8M Mini SOM?
