Half-duplex RS-485 transceiver at 1 Mbps
It integrates one driver and one receiver (1/1) in an 8-SOIC package, making it a drop-in choice for industrial and building-automation bus interfaces where the protocol requires a single master or multi-drop topology with bus-turnaround control. 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.
