Product details

5Mbps full-duplex RS-485/RS-422 transceiver for 3.3V industrial buses

3.3V supply — answers the 5V logic question

If your system has a 5V logic bus on the other side, the SN65HVD35DR's logic inputs are not 5V-tolerant at the supply — you need a level translator or a resistive divider on the driver input and receiver output if the UART or controller is 5V. The receiver outputs swing rail-to-rail on 3.3V, so a 5V MCU will see a logic-high at about 3.3V, which may or may not cross its VIH threshold depending on the family. Check the controller's input thresholds before committing.

ROHS3 compliant as well, so it passes European and global RoHS requirements without an exemption.

Standard 14-SOIC — rework-friendly

The 14-SOIC package (3.90mm body width, 0.154" pitch) is a common footprint that solders cleanly with a standard iron or hot-air station. No exposed pad, no thermal via requirement — just a straightforward SOIC layout. That makes it a field-swappable part if you carry a few in your kit and have a soldering iron.

Frequently asked questions

What is the difference between SN65HVD35DR and SN65HVD34DR?

Both are RS-485/RS-422 transceivers in the same 14-SOIC package and supply range. The SN65HVD35DR is a full-duplex part (separate driver and receiver enable pins, simultaneous TX/RX), while the SN65HVD34DR is half-duplex (shared TX/RX lines, direction controlled by driver enable). The SN65HVD35DR also has 50mV receiver hysteresis versus the SN65HVD34DR's typical 30mV. Choose the SN65HVD35DR when you need simultaneous bidirectional communication on separate twisted pairs.

Can SN65HVD35DR work with 3.3V supply?

It will operate correctly on a 3.3V rail with no additional regulation needed.
