It handles one driver and one receiver on a single channel, with a data rate up to 10 Mbps over twisted-pair cabling.
10 Mbps signaling and 30 mV hysteresis — what they mean on the bus
At 10 Mbps, this transceiver supports the faster end of Profibus and similar RS-485 networks where cable lengths stay under a few hundred meters. The half-duplex architecture means the driver and receiver share the same bus pair, so the firmware must manage direction control via the driver enable pin — a standard pattern for RS-485 nodes.
Temperature grade and package — industrial deployment
The 8-PDIP package (supplier device package 8-PDIP) is through-hole, which simplifies hand-assembly and field replacement. For a production board that already uses through-hole connectors and terminal blocks, staying with a DIP transceiver avoids a mixed-assembly step.
TI lists the SN65HVD485EPG4 as Active. The base product number is 65HVD485, and the G4 suffix indicates a lead-free / RoHS-compliant finish on the DIP package — the same die as the standard SN65HVD485EP, just in the green plating variant.
