Detailed Description

MAX13431EETB is a Specialized IC from the MAX1343xE family, designed as a robust RS-485/RS-422 transceiver for half-duplex multipoint communication. It runs from a single 3.3 V supply and is engineered for harsh industrial environments with strong ESD protection, true fail-safe receiver behavior, hot-swap tolerance, and low power consumption. Compact surface-mount package with an exposed thermal pad helps heat dissipation and high-density PCB layouts.

Key Features

3.3 V single-supply operation

Half-duplex RS-485/RS-422 transceiver

Strong ESD protection on bus pins (±15 kV-class, see datasheet for exact method/rating)

True fail-safe receiver on open, shorted, or idle bus

Hot-swap capable, glitch-free on power-up

Low quiescent current and shutdown mode for power savings

Reduced unit load receiver to support many nodes on the same bus

High noise immunity and robust bus fault protection

Wide industrial temperature support (see datasheet for exact range)

Pinout optimized for standard A/B bus lines and logic control pins

Key Advantages

Reliable field operation due to strong ESD and fail-safe design

Simplifies system bring-up and maintenance with hot-swap tolerance

Fits space-constrained designs thanks to compact leadless package

Power-friendly for battery-backed or always-on systems

Drop-in for many RS-485/RS-422 half-duplex links used in industrial networks

Packaging

Package/Case: 1057 (manufacturer case code)

Surface-mount, leadless QFN/TQFN style with exposed thermal pad for improved thermal performance

Lead-free, RoHS-compliant materials

Shipped in tape-and-reel for automated pick-and-place

Typical pin functions: DI, RO, DE, RE, A, B, VCC, GND, exposed pad (tie EP to ground as recommended)

Thermal characteristics such as θJA and power dissipation limits are defined in the datasheet and depend on PCB layout and airflow

Electrical limits (bus voltage range, ESD levels, driver output swing, receiver thresholds, current consumption, timing parameters) are specified in the datasheet
