RS-485 transceiver for 5 V industrial buses
It is specified for data rates up to 300 kbps, with receiver hysteresis of 50 mV to reject noise on long cable runs.
At 300 kbps the THVD1500DR targets the Profibus and Modbus segments that run at lower baud rates for noise immunity over twisted-pair runs of 100 metres or more. If your design needs 10 Mbps or faster, this part is not the fit — look at the THVD1550 or THVD1429 for higher-speed RS-485. The 50 mV hysteresis helps maintain a clean logic level on a loaded bus with common-mode shifts, which is the typical failure mode on long cables in electrically noisy environments.
Supply and temperature — the BOM-fit check
It is not a 3.3 V device — if your system is 3.3 V only, you will need a regulator or a different transceiver. No AEC-Q100 grade is listed, so for automotive under-hood use verify the qualification separately.
ROHS3 compliance is confirmed, so it passes the EU material restrictions without exemption paperwork.
