Key ratings — the so-what for the BOM
Full-duplex operation means the driver and receiver are active simultaneously. That requires four wires on the bus (two for transmit, two for receive) but eliminates the turnaround delay that half-duplex parts need when switching direction. If your protocol is full-duplex at the controller, this transceiver matches the bus architecture directly.
