MAX3535EEWI+T

The MAX3535EEWI+T is a +3V to +5V, 2500Vrms isolated RS485/RS422 transceiver with ±15kV ESD protection in 28 pin WSOIC package. This full duplex transceiver provides2500Vrms of galvanic isolation between RS485/RS422 side & processor or control logic side. This device allows fast, 1000Kbps communication across an isolation barrier when common-mode voltages (i.e. the ground potentials) on either side of barrier are subject to large differences. Isolation is achieved through integrated high voltage capacitors. It features a 420KHz transformer driver that allows power transfer to RS485 side using an external transformer. It includes one differential driver, one receiver and internal circuitry to send RS485 signals and control signals across isolation barrier (including isolation capacitors). Device operates with a single power supply and improved secondary supply range of IC allows use of step-down transformers for +5V operation resulting in considerable power savings.
