RS-485/RS-422 link for noisy industrial backplanes
The MAX14856GWE+ is a full-duplex transceiver that handles RS-485 and RS-422 signaling at 500 kbps, with a single driver and single receiver on board. The 20 mV receiver hysteresis cleans up marginal signals on long cable runs — a common failure signature on factory-floor RS-485 buses where the last node sees a degraded differential.
The receiver hysteresis of 20 mV is fixed — no external resistor to set it, which saves a pass on the layout. Industrial temperature grade (-40°C to +105°C) means this part is at home in outdoor telecom cabinets, factory-floor I/O blocks, and HVAC controllers where the ambient inside the enclosure hits 85°C and the self-heating from the transceiver adds another 10-15°C.
Active production, ROHS3, no second-source on record
If you are qualifying a second source for a high-volume build, the parametric search across the MAX14856 family will turn up variants with different package options or extended temperature ranges, but the 16-SOIC wide-body footprint is specific to this order code.
