Half-duplex RS-485 transceiver for mixed-voltage industrial buses
It integrates one driver and one receiver, and its 3V to 5.5V supply range means it can sit on a 3.3V controller rail or a traditional 5V bus without a level shifter. The 35 mV receiver hysteresis helps reject noise on long cable runs typical of factory-floor Modbus or BACnet links.
Supply voltage flexibility — one part for 3.3V and 5V buses
A 3.3V-only RS-485 transceiver locks you into a voltage domain; this part works across both, so a BOM that spans 3.3V MCUs and 5V legacy peripherals can use the same transceiver. No extra regulator or level translator needed on the supply side. The half-duplex architecture with one driver and one receiver is the standard for two-wire RS-485 buses where direction is toggled by a microcontroller GPIO.
For a storeroom or BOM planner, that means no last-time-buy scramble in the next few years. Store the reels dry — the SOIC-8 package is MSL 1 or 3 depending on date code, but standard handling applies.
