Product Details The MAX14853GWE+ is an isolated RS-485 and RS-422 transceiver designed for reliable full-duplex communication in industrial and embedded electronic systems. It provides galvanic isolation between the UART-side interface and the cable-side communication circuitry, helping reduce the effects of ground potential differences and electrical noise in connected equipment.The device supports communication speeds up to 500kbps and includes one driver and one receiver channel. Its quarter-unit-load receiver allows up to 128 transceivers to share a communication bus, making the device suitable for distributed industrial networks and multi-node control systems.A key feature of the MAX14853GWE+ is its integrated isolation architecture. The device provides 2.75kV RMS isolation withstand voltage for 60 seconds and incorporates an integrated transformer driver for transferring power to the cable side through an external transformer. An integrated LDO further simplifies the isolated power architecture and can reduce the number of external circuit elements required in the system.The transceiver is designed for robust communication environments. Driver outputs and receiver inputs provide ±35kV HBM ESD protection, while integrated fail-safe circuitry maintains a logic-high receiver output when communication inputs are open or shorted. The MAX14853 also incorporates a receiver deglitch filter and slew-rate-limited outputs to improve noise immunity and communication stability.The MAX14853GWE+ is supplied in a wide-body 16-pin SOIC package and operates across a -40°C to +105°C temperature range. Its combination of isolation, integrated power-transfer functions and RS-485/RS-422 communication makes it suitable for industrial automation equipment, HVAC controllers, power meters and programmable logic controllers.For system designers, the MAX14853GWE+ can simplify isolated serial communication interfaces where protection against ground loops, transient disturbances and electrical noise is important. It can be integrated into control boards, industrial communication equipment and embedded systems that require dependable RS-485 or RS-422 connectivity.
