+3V to +5V, 2500VRMS Isolated RS-485/RS-422 Transceivers with 【15kV ESD Protection
General DescriptionThe MAX3535E/MXL1535E isolated RS-485/RS-422 full-
duplex transceivers provide 2500VRMSof 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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to

Note 3:VISOis the voltage difference between GND1 and GND2.
Note 4:The maximum data rate is specified using the maximum jitter value according to the formula: data rate = 1 / (4tJ). See the
Skew sectionfor more information.
Note 5:Initial startup time is the time for communication to recover after a fault condition. Internal communication timeout fault time
is the time before a fault is indicated on RE,after internal communication has stopped.
