The 35 mV of receiver hysteresis provides a noise margin on the differential bus that rejects common-mode interference typical in factory-floor cabling runs. ## Supply voltage and 5V logic compatibility The logic inputs (driver enable, data in) are referenced to this supply rail, not to 5 V. If the host microcontroller or UART uses 5 V logic levels, a voltage-level translator or resistive divider is required on the logic-side pins to avoid exceeding the absolute maximum ratings on the logic inputs.","metaTitle":"SN65HVD12DRG4 RS-485/RS-422 Transceiver, 1 Mbps, 8-SOIC","metaDescription":"TI SN65HVD12DRG4 half-duplex RS-485/RS-422 transceiver, 1 Mbps data rate, 3V-3.6V supply, 35 mV hysteresis, -40°C to 85°C.
