MAX1482CSD+T

Drivers, Receivers, Transceivers Overview

The MAX1482CSD+T is a full-duplex RS-485/RS-422 transceiver in a 14-pin SO package. It operates from a single +5V supply (4.75V to 5.25V) with a typical operating current of 20µA and a shutdown current of 0.1µA. The device supports data rates up to 250kbps, features slew-rate-limited drivers for EMI reduction, and includes thermal shutdown and short-circuit protection. It offers a -7V to +12V common-mode input range and an 1/8-unit-load receiver impedance.

Drivers, Receivers, Transceivers Feature Summary

• Slew-rate-limited drivers minimize electromagnetic interference and reduce signal reflections on improperly terminated cables.
• Low-power architecture provides 20µA operating current and a 0.1µA shutdown mode for energy conservation.
• Integrated thermal shutdown and foldback current limiting protect the driver outputs against excessive power dissipation and short circuits.

Drivers, Receivers, Transceivers Applications

• Low-power RS-485 and RS-422 communication networks
• Transceivers designed for EMI-sensitive industrial applications
• Industrial-control local area networks requiring high node density

Drivers, Receivers, Transceivers Procurement Notes

Verify the component matches the specific full-duplex MAX1482 variant rather than the half-duplex MAX1483. Confirm the suffix indicates the commercial temperature range (0°C to +70°C). Ensure the package type corresponds to the 14-pin SO format specified for this part number.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing full-duplex RS-485 or RS-422 systems that require low quiescent current. The 1/8-unit-load input impedance allows for bus configurations supporting up to 256 transceivers. Verify that the required data rate does not exceed 250kbps and that the application environment falls within the commercial temperature limits.

Drivers, Receivers, Transceivers Part Context

This device belongs to the MAX1482/MAX1483 family of low-power transceivers manufactured by Analog Devices Inc./Maxim Integrated. The MAX1482CSD+T specifically denotes the full-duplex version housed in a 14-pin Small Outline package with a commercial temperature rating.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX1483CSD+T serves as a functional substitute if the application requires only half-duplex communication. Other compatible options include the MAX1487 series for similar low-power RS-485 requirements.
