It integrates one driver and one receiver, operates from a 3V to 5.5V supply, and delivers a data rate of 500 kbps. The receiver includes 20 mV of hysteresis for noise rejection on long cable runs. Rated for -40°C to 105°C, this part suits factory automation, building management, and outdoor telecom equipment where the bus lines leave the cabinet. ## Active production and sourcing posture The MAX14857GWE+T carries an Active product status per the manufacturer — no end-of-life notice, no last-time-buy clock. It is ROHS3 compliant. ## Full-duplex operation and 500 kbps data rate — fit for polled networks Full-duplex means the driver and receiver can operate simultaneously, which is useful for multi-drop RS485 networks that need continuous bus monitoring while transmitting. The 500 kbps rate covers most industrial fieldbus and Modbus applications running at 115.2 kbps or 230.4 kbps, with margin for cable capacitance and stub lengths. The 20 mV hysteresis on the receiver input rejects common-mode noise picked up on twisted-pair runs in electrically noisy environments like motor drives and variable-frequency drives. ## Package and supply considerations for the layout Housed in a 16-SOIC (0.295\", 7.50 mm width) package, the part's footprint matches the standard wide-body SOIC-16 land pattern. The 3V to 5.5V supply range means it can drop into a 3.3V-only backplane or a legacy 5V system without a local regulator. The industrial temperature grade (-40°C to 105°C) covers unheated enclosures, engine compartments, and rooftop telecom cabinets.","metaTitle":"MAX14857GWE+T RS485/RS422 Transceiver, Full Duplex, 500 kbps","metaDescription":"MAX14857GWE+T RS485/RS422 full-duplex transceiver.
