THVD2410: Driving RE and RE from a single pin

Part Number: THVD2410


I've to design a RS485 half-duplex communication line, and I'm running out of microcontroller pin to drive RE and DE separately; I'm pretty sure I've done it in the past (with another chip), but I'd like a confirmation from you fellow engineers if this solution is working:

when RS485_DIR signal is LOW, rx is enabled and tx is disabled

when RS485_DIR signal is HIGH, rx is disabled and tx is enabled

I've no need to put the chip in standby or in low power mode

Thank you very much for your time, best regards
