20 Mbps full-duplex RS-485 transceiver for industrial buses
The Texas Instruments SN65HVD74DGK is a full-duplex RS-422/RS-485 transceiver delivering 20 Mbps data rate over a single differential pair, with one driver and one receiver in an 8-VSSOP package. The 70 mV receiver hysteresis provides built-in noise margin on long cable runs, reducing the need for external filtering in electrically noisy factory-floor or motor-drive environments.
For BOM planning, this removes the urgency to qualify a drop-in replacement or stockpile for a looming phase-out.
