MAX14856/MAX14858

5kV

Isolated 500kbps/25Mbps Full-Duplex

RS-485/RS-422 Transceivers

with ±35kV ESD Protection

RMS

General Description

The MAX14856/MAX14858 isolated RS-485/RS-422

transceivers provide 5000V (60s) of galvanic

isolation 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 (MAX14856) or 25Mbps

(MAX14858).

Beneﬁts and Features

● High-Performance Transceiver Enables Flexible Designs

• Integrated LDO for Cable Side Power

• Compliant with RS-485 EIA/TIA-485 Standard

• 500kbps (MAX14856)/25Mbps (MAX14858)

Maximum Data Rate

RMS

• Allows Up to 128 Devices on the Bus

● Integrated Protection Ensures for Robust

Communication

• ±35kV ESD (HBM) on Driver Outputs/Receiver Inputs

• 5kV

Withstand Isolation Voltage for 60

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.

IORM

Maximum Working-Isolation Voltage

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 the cable side or UART side

power supplies are below functional levels.

• 848V

RMS

)

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

● UL According to UL1577

● cUL According to CSA Bulletin 5A

The devices 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
