It hits 1 Mbps on the bus, which is the sweet spot for industrial fieldbus links like Modbus RTU or Profibus at that speed — fast enough for most sensor and actuator networks without the edge-rate headaches of faster parts. The 50 mV of receiver hysteresis cleans up noise on long cable runs, so you get a clean logic output even when the differential signal has picked up common-mode junk. If your board runs a 5 V bus, you will need a level translator or a different transceiver. It is not AEC-Q100 qualified, so skip it for under-hood or chassis-mounted automotive designs. If you are dual-sourcing, the base number 65HVD32 covers the whole family, so the SN65HVD32D (tube) or SN65HVD32DG4 are the same die in different shipping media.","metaTitle":"SN65HVD32DR RS-485/RS-422 Transceiver, 1 Mbps, 8-SOIC","metaDescription":"TI SN65HVD32DR full-duplex RS-485/RS-422 transceiver, 1 Mbps data rate, 3V-3.6V supply, -40°C to 85°C, 8-SOIC.
