MAX1484CUB+

Drivers, Receivers, Transceivers Overview

The MAX1484CUB+ is a software-selectable, full-duplex RS-422/RS-485 transceiver housed in a 10-pin µMAX package. It operates from a single +5V supply with a typical quiescent current of 300µA and supports data rates up to 12Mbps. The device features one driver and one receiver with a 1/8-unit-load input impedance, enabling up to 256 transceivers on the bus. Driver outputs are short-circuit current limited and protected by thermal shutdown circuitry. The receiver includes a fail-safe feature that guarantees a logic-high output when the input is open.

Drivers, Receivers, Transceivers Feature Summary

• Compact 10-pin µMAX package design for space-constrained applications
• High-speed operation supporting up to 12Mbps data transmission
• Integrated thermal-shutdown protection against excessive power dissipation
• Fail-safe receiver input ensuring logic-high output during open-circuit conditions

Drivers, Receivers, Transceivers Applications

• Low-power RS-422/RS-485 communications
• Industrial-control local area networks
• Hand-held equipment
• Battery-powered equipment

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'C' indicates the commercial temperature range (0°C to +70°C) and '+T' denotes tape-and-reel packaging. Confirm the component is sourced from Analog Devices or Maxim Integrated to ensure authenticity. Check for RoHS compliance documentation as required by your manufacturing standards. Ensure the ordering information matches the exact pinout and electrical specifications provided in the official datasheet.

Drivers, Receivers, Transceivers Selection Notes

Select the MAX1484CUB+ for applications requiring full-duplex RS-422 communication at high speeds up to 12Mbps. This part is suitable where board space is limited due to its small 10-pin µMAX footprint. It is not appropriate for half-duplex-only designs without utilizing the H/F pin configuration correctly, nor for slew-rate-limited EMI-sensitive applications which require the MAX1481 or MAX1485 variants.

Drivers, Receivers, Transceivers Part Context

The MAX1484 is part of the MAX1481/MAX1484/MAX1485/MAX1486 family of high-speed transceivers. While functionally equivalent to industry-standard parts like the MAX491 and 75180, it offers a significantly smaller package size. Unlike the MAX1485 and MAX1486, the MAX1484 is fixed in full-duplex mode and lacks software-selectable half-duplex capability.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX1484 is functionally equivalent to the MAX491 and 75180. Verify pin compatibility and electrical characteristics before substituting these legacy components.
