Product details

250 kbps RS-485 transceiver for industrial buses

The 80 mV receiver hysteresis cleans up noisy bus signals, reducing false start bits on long or unshielded twisted-pair runs.

For procurement, that removes the single-source obsolescence risk that haunts older RS-485 parts.

Pin-compatible sibling: SN65HVD72DR

The SN65HVD72DR shares the same electrical specs — 250 kbps, half-duplex, 3V to 3.6V supply — but comes in an 8-SOIC package, which is a larger, more widely used footprint. The DGKR variant in 8-VSSOP saves about 30% board area, critical for space-constrained designs. Both are active and pin-compatible, so you can swap between them with a layout change.

Frequently asked questions

What is the difference between SN65HVD72DGKR and SN65HVD72DR?

The DGKR comes in an 8-VSSOP package (smaller), while the DR uses an 8-SOIC (larger). They are pin-compatible, so a layout change handles the swap.
