Its headline rating is the 50 Mbps data rate, which sustains high-throughput serial links — think encoder feedback, motor-drive command buses, or high-speed sensor arrays — without dropping into half-duplex arbitration.
No derating needed up to the full 125°C junction — the part keeps its 50 Mbps throughput across the entire range.
The SN65HVD1477DGK is a full-duplex transceiver at 50 Mbps; the SN65HVD1476 is a half-duplex variant at a lower data rate. They are not pin-compatible or direct replacements — the duplex mode and data rate differ. Check the TI datasheet for the full family matrix.
Yes — it is a full-duplex transceiver, meaning it can simultaneously transmit and receive on separate twisted pairs without bus-turnaround delays.
