50 Mbps full-duplex RS-485 — what the data rate means for the bus
That data rate puts it in the high-speed tier — think motion-control encoder links, high-resolution camera trigger lines, or backplane communication where you need to move a few hundred bytes in under a millisecond. The full-duplex capability means separate transmit and receive paths, so you don't waste bus cycles turning the driver around; the 1/1 driver/receiver count is exactly what a point-to-point link needs.
125°C junction — industrial and motor-drive environments
The 70 mV receiver hysteresis cleans up noise on long cable runs — a common pain point in factory-floor RS-485 installations where ground potential differences and coupled motor noise eat signal margin.
TI lists the SN65HVD1477DR as Active. That means no last-time-buy deadline, no end-of-life notice on the horizon. The base product number is 65HVD1477, so any future PCNs or die revisions will track under that root.
