5V-only full-duplex transceiver for 10 Mbps RS-485/RS-422 buses
The Texas Instruments SN65HVD1793DR is a full-duplex RS-422/RS-485 transceiver in a 14-SOIC package, rated for 10 Mbps signaling on differential buses.
10 Mbps data rate and the cable-length tradeoff
At 10 Mbps the SN65HVD1793DR supports short-haul runs — typically under 100 meters — where the bit period is tight enough that cable capacitance and stub length matter. For longer runs at lower rates the same part works fine; the driver slew is not limited, so the designer controls edge rate through termination and stub topology rather than a slow-mode pin. The 50 mV hysteresis on the receiver helps reject common-mode noise that couples onto the twisted pair in industrial environments.
