EVALUATION KIT AVAILABLE  
MAX14852/MAX14854  
2.75kV

RS-485/RS-422 Transceivers  
with ±35kV ESD Protection  
RMS  
General Description  
The MAX14852/MAX14854 isolated RS-485/RS-422  
Benefits and Features  
● High-Performance Transceiver Enables Flexible Designs  
• Integrated LDO for Cable Side Power  
• Compliant with RS-485 EIA/TIA-485 Standard  
• 500kbps (MAX14852)/25Mbps (MAX14854) Maximum  
Data Rate  
transceivers provide 2750V (60s) of galvanic isola-  
RMS  
tion between the cable side (RS-485/RS-422 driver/  
receiver side) and the UART side of the device. Isolation  
improves communication by breaking ground loops and  
reduces noise when there are large differences in ground  
potential between ports. These devices allow for robust  
communication up to 500kbps (MAX14852) or 25Mbps  
(MAX14854).  
• Allows Up to 128 Devices on the Bus  
● Integrated Protection Ensures for Robust Communication  
• ±35kV ESD (HBM) on Driver Outputs/Receiver Inputs  
• 2.75kV  
Withstand Isolation Voltage for 60  
RMS  
Seconds (V  
)
The devices include one drive channel and one receive  
channel. The receiver is 1/4-unit load, allowing up to 128  
transceivers on a common bus.  
ISO  
• 630V  
Maximum Repetitive Peak-Isolation

Voltage (V  
IORM  
• 445V  
Maximum Working-Isolation Voltage  
RMS  
Integrated true fail-safe circuitry ensures a logic-high on  
the receiver output when inputs are shorted or open.  
Undervoltage lockout disables the driver when cable side  
or UART-side power supplies are below functional levels.  
(V  
)
IOWM  
• > 30 Years Lifetime at Rated Working Voltage  
• Withstands ±10kV Surge per IEC 61000-4-5  
• Thermal Shutdown  
The driver outputs and receiver inputs are protected  
from ±35kV electrostatic discharge (ESD) to GNDB on  
the cable side, as specified by the Human Body Model  
(HBM).  
Safety Regulatory Approvals Pending  
● UL According to UL1577  
● cUL According to CSA Bulletin 5A  
The MAX14852/MAX14854 are available in a wide-body  
16-pin SOIC package and operate over the -40°C to  
+105°C temperature range.  
Applications  
● Industrial Automation Equipment  
● Programmable Logic Controllers  
● HVAC  
● Power Meters
