What the 16 Mbps half-duplex rating means for your bus
The MAX13431EEUB+ is a single RS485/RS422 transceiver with one driver and one receiver (1/1), operating in half-duplex mode over a single twisted-pair bus. Rated at 16 Mbps, the data rate ceiling is high enough for Profibus DP, Modbus RTU at high baud rates, or custom high-speed serial links — but the actual throughput depends on cable length and stub length; at 16 Mbps the practical bus length is typically under 100 meters. The 15 mV receiver hysteresis filters noise on long or electrically noisy bus runs, reducing false edge triggering without external filtering.
The supplier device package is 10-uMAX/uSOP (also known as 10-MSOP), a common footprint shared across many Analog Devices transceivers — layout reuse across a family of parts is straightforward.
Lifecycle and compliance snapshot
RoHS3 compliant (2011/65/EU + 2015/863), with no restricted substances above the threshold — fits global environmental requirements without exemption paperwork.
