Product details

The 70 mV hysteresis helps reject noise on longer bus stubs, reducing the need for external termination tweaks.

For production BOM lines, this part can be dual-sourced with other full-duplex RS-485 transceivers in the same 8-SOIC footprint, though the exact pin-compatible alternative depends on the enable-pin logic (this variant does not have an enable pin per the evidence).

Frequently asked questions

Where can I buy the SN65HVD71DR and get a price?

The SN65HVD71DR is available to order through independent distribution. Submit an RFQ for current pricing and confirmed availability — lead times and stock levels are verified at quote time.

What is the data rate of the SN65HVD71DR?

The SN65HVD71DR is rated for 400 kbps data rate, suitable for industrial fieldbus protocols like Modbus RTU at typical baud rates.

Is the SN65HVD71DR full duplex?

Yes, the SN65HVD71DR is a full-duplex transceiver, meaning it can transmit and receive simultaneously over separate twisted pairs — useful for point-to-point links where bidirectional traffic is continuous.

What is the difference between the SN65HVD71DR and the SN65HVD72DR?

The primary difference is the data rate: the SN65HVD71DR is rated for 400 kbps, while the SN65HVD72DR supports higher speeds (typically 20 Mbps or more in the family). Check the specific sibling datasheet for exact rate and enable-pin differences.
