Product details

Full-duplex RS-485/RS-422 transceiver for 3.3V buses

The 5 Mbps data rate covers most industrial fieldbus segments (Profibus, Modbus RTU at higher baud rates) and allows enough margin for cable lengths up to a few hundred metres with proper termination. The 50 mV hysteresis filters out reflections and common-mode noise that would otherwise cause bit errors on unterminated stubs. For a 3.3V-only system, the supply range confirms direct connection to the logic rail without a separate transceiver supply — no level shifter needed.

Frequently asked questions

Is the SN65HVD34D compatible with 3.3V systems?

Yes, the supply voltage range of 3V to 3.6V makes it directly compatible with 3.3V logic rails without an external regulator or level translator.

Does the SN65HVD34D have a shutdown mode?

The evidence does not indicate a shutdown or low-power mode for this part. The device is always in active receive or drive state when powered.
