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. ## Package and footprint — 8-VSSOP for space-constrained boards","metaTitle":"SN65HVD74DGK RS-422/RS-485 Transceiver, 20 Mbps, Full Duplex","metaDescription":"Texas Instruments SN65HVD74DGK full-duplex RS-422/RS-485 transceiver, 20 Mbps data rate, 3V–3.6V supply, –40 to 125°C, 8-VSSOP.

The SN65HVD74DGK supports 20 Mbps data rate, while the SN65HVD72DGK is a lower-speed variant.
