Detailed Description

High-speed quad RS-422/RS-485 receiver (0 drivers, 4 receivers) for industrial communications. Operates from a 5V supply (4.5V to 5.5V), supports up to 35 Mbps data rate, and works across a wide -40°C to +125°C temperature range. Compact 32-TQFN (5x5 mm) package with exposed thermal pad. RoHS3 compliant. Surface-mount for space-sensitive designs. Base product number MAX14890

Key Features

Quad differential receivers for RS-422 and RS-485 (0/4 configuration)

High data rate up to 35 Mbps for fast multidrop or point-to-point links

Wide industrial temperature range -40°C to +125°C

Single 5V supply (4.5V to 5.5V)

Compact 32-pin TQFN 5x5 mm with exposed pad for better heat dissipation

RS-422/RS-485 compliant differential inputs

Robust design for industrial environments (strong ESD and EMC behavior; see datasheet for exact ratings)

RoHS3 compliant, lead-free

Key Advantages

Four receivers in one IC reduce board count and save PCB area

35 Mbps throughput enables modern, high-speed RS-485 networks

Industrial-grade reliability across temperature extremes

Exposed pad improves thermal performance in dense designs

Simplifies multi-channel data acquisition, monitoring, and bus diagnostics

Proven ADI/Maxim quality with stable performance over time

Packaging

Semiconductor package type: 32-TQFN (5x5 mm) and 32-WFQFN with exposed thermal pad

Body size: approximately 5.0 mm x 5.0 mm, low-profile height (refer to datasheet for exact height)

Pin count and layout: 32 pins total plus large exposed pad for heat and ground; multiple differential input pairs and logic outputs; power and ground pins; enable and control pins (see pinout in datasheet)

Leadframe and molding: copper leadframe with molded epoxy compound; industry-standard lead finish (refer to datasheet/PCN for exact finish)

Thermal characteristics: exposed pad must be soldered to a ground plane for optimal heat spreading; detailed thermal resistance values provided in datasheet

Electrical properties: 5V supply (4.5V to 5.5V), RS-422/RS-485 compliant receivers, up to 35 Mbps signaling

Mounting: surface-mount technology (SMT)

Shipment packaging: Tray

Moisture sensitivity level and reflow profile: see datasheet for MSL rating and recommended reflow parameters

Lifecycle

Status: Active and suitable for new designs based on available information

Not nearing discontinuation as of current guidance; always confirm latest PCNs and lifecycle updates

Equivalent or alternative models (verify pinout, timing, voltage, and data rate carefully)
