MAX3471EUA+T

Drivers, Receivers, Transceivers Overview

The MAX3471EUA+T is a half-duplex differential transceiver designed for RS-485 and RS-422 communication in lithium battery-powered systems. It operates on a single supply voltage ranging from +2.5V to +5.5V, ensuring compatibility with battery discharge curves. The device features an ultra-low typical supply current of 1.6µA when the receiver is enabled and the driver is disabled. It supports data rates up to 64kbps and includes true fail-safe receiver inputs that guarantee a logic-high output when inputs are open or shorted. The component is housed in an 8-pin µMAX package and is rated for an operating temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Ultra-low power consumption optimized for extended battery life in portable applications
• True fail-safe receiver input guarantees a logic-high state during bus idle or fault conditions
• Slew-rate limited drivers minimize electromagnetic interference (EMI) and reduce signal reflections
• Wide common-mode input voltage range accommodates high-voltage noise environments

Drivers, Receivers, Transceivers Applications

• Remote meter reading systems
• Battery-powered differential communications networks
• Level translation interfaces

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'EUA' to confirm the industrial temperature grade (-40°C to +85°C) and the µMAX package type. Ensure the '+T' designation aligns with reel packaging requirements if applicable. Cross-reference the manufacturer's latest documentation to confirm current production status and availability constraints before finalizing procurement plans.

Drivers, Receivers, Transceivers Selection Notes

Select this component for low-speed serial communication links where power efficiency is critical. The 1/8-unit-load receiver input allows for connecting up to eight devices on the bus without additional buffering at lower supply voltages. Verify that the required data rate does not exceed 64kbps and that the system environment falls within the specified electrical and thermal limits.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX3471 family of half-duplex transceivers manufactured by Analog Devices / Maxim Integrated. The 'E' suffix denotes the extended industrial temperature range, while 'U' indicates the µMAX package. The 'A' typically signifies lead-free and RoHS compliance. This series is engineered specifically for low-power, long-battery-life applications compared to standard voltage transceivers.

Drivers, Receivers, Transceivers Replacement Considerations

Direct pin-compatible alternatives within the same family include the MAX3471CUA+T for commercial temperature ranges. Other compatible options may include the MAX13487 or MAX13488 series, though interface configurations and pinouts must be verified against the original design schematic to ensure functional equivalence.
