MXL1535EEWI+

MXL1535EEWI+ is an isolated RS-485/RS-422 full-duplex transceiver that provides 2500VRMS of galvanic isolation between the RS-485/RS-422 side and the processor or control the logic side. It features a 420KHz transformer driver that allows power transfer to the RS-485 side using an external transformer. It includes one differential driver, one receiver, and internal circuitry to send the RS-485 signals and control signals across the isolation barrier (including the isolation capacitors). The MXL1535E RS-485 receivers are 1/8 unit load, allowing up to 256 devices on the same bus. It features true fail-safe circuitry. The driver outputs and the receiver inputs are protected from ±15kV electrostatic discharge (ESD) on the interface side, as specified in the human body model (HBM). It is used in applications such as isolated RS-485 systems, systems with large common-mode voltages, industrial-control local area networks, and telecommunications systems.
