For a 500-meter cable run at 400 kbps, signal rise time and stub length still need careful termination; the 70 mV hysteresis helps keep noise from false-starting a bit. ## Full-duplex with 1/1 driver/receiver count Full-duplex operation means separate twisted pairs for transmit and receive, so the bus can send and receive simultaneously. The 1/1 driver/receiver ratio is standard for point-to-point or multi-drop where only one node transmits at a time on each pair. If your topology needs half-duplex (shared pair), the SN65HVD1471 still works with the driver enable toggled, but a dedicated half-duplex part like the SN65HVD1470 would save a pair. ## Package and footprint: 8-VSSOP The 8-VSSOP (also listed as 8-TSSOP / 8-MSOP with 0.118-inch width) is a compact surface-mount package. The footprint is shared across the SN65HVD147x family, so swapping between full- and half-duplex variants within the series requires no board layout change — only the firmware and connector wiring differ.","metaTitle":"SN65HVD1471DGKR RS422/RS485 Transceiver, Full Duplex","metaDescription":"Texas Instruments SN65HVD1471DGKR RS422/RS485 full-duplex transceiver, 400kbps, 3V-3.6V supply, -40°C to 125°C, 8-VSSOP.

The RS-485 bus pins themselves are differential and tolerate common-mode voltages well beyond the supply, but the logic-side pins must stay within the 3.6V absolute maximum."},{"question":"What is the replacement for SN65HVD1471DGKR?","answer":"No official replacement or successor is listed by Texas Instruments for the SN65HVD1471DGKR.
