Description
The MAX3535E/MXL1535E isolated RS-485/RS-422 full- duplex transceivers provide 2500VRMS of galvanic isola- tion between the RS-485/RS-422 side and the processor or control logic side. These devices allow fast, 1000kbps communication across an isolation barrier when the common-mode voltages (i.e., the ground potentials) on either side of the barrier are subject to large differences. Isolation is achieved through integrat- ed high-voltage capacitors. The MAX3535E/MXL1535E also feature a 420kHz transformer driver that allows power transfer to the RS-485 side using an external transformer. The MAX3535E/MXL1535E include 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 MAX3535E/ MXL1535E RS-485 receivers are 1/8 unit load, allowing up to 256 devices on the same bus. The MAX3535E/MXL1535E feature true fail-safe circuitry. The driver outputs and the receiver inputs are protected from ±15kV electrostatic discharge (ESD) on the inter- face side, as specified in the Human Body Model (HBM). The MAX3535E/MXL1535E feature driver slew-rate select that minimizes electromagnetic interference (EMI) and reduces reflections. The driver outputs are short-cir- cuit and overvoltage protected. Other features are hot- swap capability and isolation-barrier fault detection. The MAX3535E operates with a single +3V to +5.5V power supply. The improved secondary supply range of the MAX3535E allows the use of step-down transformers for +5V operation, resulting in considerable power sav- ings. The MXL1535E operates with a single +4.5V to +5.5V power supply. The MXL1535E is a function-/pin- compatible improvement of the LTC1535. The MAX3535E/MXL1535E are available over the commer- cial 0°C to +70°C and extended -40°C to +85°C temper- ature ranges.
