The 20 Mbps data rate supports high-throughput links like encoder feedback or multi-drop sensor networks where update speed is critical. Full-duplex operation means separate transmit and receive pairs, doubling throughput compared to half-duplex and eliminating turnaround delays — useful for polled or continuous-stream protocols. The 70 mV hysteresis on the receiver input improves noise immunity on long or noisy cables, reducing bit errors without external filtering.

Frequently asked questions
What is the closest pin-compatible alternative to SN65HVD1474DR?
Within the same TI family, the SN65HVD1474 is the base part number; the 'DR' suffix indicates tape-and-reel packaging. Pin-compatible full-duplex RS-485 transceivers from TI include the SN65HVD1475 (higher data rate) and SN65HVD1473 (lower data rate), but verify the exact speed and supply specs for your application.
How to use SN65HVD1474DR in an RS-485 network?
For full-duplex operation, connect the driver outputs (Y, Z) to the transmit twisted pair and the receiver inputs (A, B) to the receive pair. Terminate both ends with 120Ω resistors. The 70 mV hysteresis helps reject noise on long runs. Supply decoupling with 0.1 µF ceramic close to the VCC pin is recommended.
