Yes! The logic gates from a RS485/422. Most likely the signal are level shifted. Below is an except form Low power RS-485/RS-422 transceiver ST485B, ST485C datasheet.

Below is an another similar part. PROFIBUS Compliant 6kV VDE-Reinforced Isolated RS-485 Transceiver ISL32741E. The example circuit is converting signal 3.3V-5V and 5V-3.3V.
