MAX14852/MAX14854

2.75kV

Isolated 500kbps/25Mbps Full-Duplex

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

)

PEAK

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.

)

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
