EVALUATION KIT AVAILABLE

MAX14775E/MAX14776E

±65V Fault Protected 500kpbs/20Mbps

Half-Duplex RS-485/RS-422 Transceivers

General Description

Beneﬁts and Features

● Integrated Protection Ensures for Robust

The MAX14775E/MAX14776E fault-protected RS-485/

RS-422 transceivers feature ±65V protection for overvoltage

signal faults on communication bus lines, ensuring

communication in harsh industrial environments.

Each device contains one driver and one receiver and

operates over the 3V to 5.5V supply range. The

MAX14775E is optimized for high-speed data rates up

to 20Mbps. The MAX14776E features slew-rate limited

outputs for data rates up to 500kbps.

Communication

•ꢀ ±65V Fault Protection Range on Driver Outputs/

Receiver Inputs

•ꢀ ±25V Common Mode Range on the Receiver Inputs

•ꢀ Large Receiver Hysteresis Increases Noise Tolerance

•ꢀ Hot-Swap Protection

•ꢀ Thermal Shutdown

● High-Performance Transceiver Enables Flexible

Designs

These transceivers are optimized for robust communication

in noisy environments. A large 200mV (typ) hysteresis on

receiver inputs ensure for high noise rejection and a fail-

safe feature guarantees a logic-high on the receiver output

when the inputs are open or shorted. Driver outputs are

protected against short-circuit conditions.

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

•ꢀ 20Mbps (MAX14775E)/500kbps (MAX14776E)

Maximum Data Rate

•ꢀ 3V to 5.5V Supply Range

•ꢀ Up to 100 Devices on the Bus

The MAX14775E/MAX14776E receivers feature a 1/3-

unit load input impedance, allowing up to 100 transceivers

on a bus.

Applications

● Industrial Field Bus Networks

● Motion Controllers

● HVAC

The MAX14775E/MAX14776E are available in 8-pin

SOIC and 8-pin TDFN-EP packages and operate over the

-40°C to +125°C temperature range.
