Product details

Half-duplex RS-485/422 transceiver for automotive and industrial bus nodes

The Texas Instruments SN65HVD1782QDRQ1 is a half-duplex RS-485/RS-422 transceiver with one driver and one receiver in an 8-SOIC package, rated for 10 Mbps data rate across a 3.3V to 5V supply range.

Supply voltage flexibility and bus compatibility

With a supply range spanning 3.3V to 5V, this transceiver can operate from a regulated 3.3V rail in a mixed-voltage design or from a 5V rail for maximum bus signal swing — the same part covers both scenarios. Protocol support for RS-485 and RS-422 means it fits both multi-drop (RS-485) and point-to-point (RS-422) topologies, common in factory automation, building management, and vehicle networks.

AEC-Q100 and 125°C junction rating

Active product status means TI continues to manufacture and support this device — no last-time-buy risk for production programs currently using it.

Frequently asked questions

Is SN65HVD1782QDRQ1 compatible with 5V supply?

Yes, the SN65HVD1782QDRQ1 operates from a 3.3V to 5V supply, so it works directly on a 5V bus rail without external regulation.

What is the difference between SN65HVD1782QDRQ1 and SN65HVD1782DR?

The SN65HVD1782QDRQ1 is the AEC-Q100 automotive-qualified version of the base SN65HVD1782DR. Both share the same half-duplex RS-485/422 transceiver core, 10 Mbps data rate, and 8-SOIC package.
