MAX1484EUB+

Drivers, Receivers, Transceivers Overview

The MAX1484EUB+T is a software-selectable, full-duplex RS-485/RS-422 transceiver housed in a 10-pin µMAX package. It operates from a single +5V supply with a voltage range of 4.75V to 5.25V and draws 300µA of quiescent current. The device supports data rates up to 12Mbps with unrestricted slew rates. It features one driver and one receiver with a 1/8-unit-load input impedance, allowing up to 256 transceivers on the bus. Operating temperatures range from -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Software-selectable half-/full-duplex operation via H/F pin
• High-speed transmission up to 12Mbps without slew-rate limiting
• Low-power consumption with 300µA typical supply current
• 1/8-unit-load receiver input impedance for high node capacity

Drivers, Receivers, Transceivers Applications

• Industrial-control local area networks
• Battery-powered equipment
• Hand-held equipment
• EMI-sensitive applications

Drivers, Receivers, Transceivers Procurement Notes

Verify the component authenticity by checking the manufacturer marking against the official datasheet specifications. Confirm the package type matches the 10-pin µMAX format and ensure the temperature grade corresponds to the E suffix (-40°C to +85°C). Cross-reference the ordering information section to validate the specific part number configuration before integration into production systems.

Drivers, Receivers, Transceivers Selection Notes

Select this component for space-constrained designs requiring full-duplex RS-422 or RS-485 communication. It is suitable for applications needing high-speed data transfer up to 12Mbps where reduced electromagnetic interference is not the primary constraint compared to speed. Ensure the system design accommodates the 10-pin µMAX footprint and provides adequate thermal management for the specified power dissipation limits.

Drivers, Receivers, Transceivers Part Context

This device belongs to the MAX1481/MAX1484/MAX1485/MAX1486 family of high-speed transceivers. While functionally similar to industry-standard parts like the MAX491 and 75180, it offers a significantly smaller 10-pin µMAX package. The MAX1484 variant specifically provides full-duplex operation with high-speed capabilities, distinguishing it from the slew-rate-limited MAX1481 and the selectable duplex MAX1485/1486 models.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX1484EUB+ is functionally equivalent to the MAX491 and 75180. However, due to the distinct 10-pin µMAX package, direct pin-to-pin replacement may require PCB layout modifications. Verify that the replacement solution supports the required 12Mbps data rate and full-duplex architecture.
