MAX3491CSD

Overview

The MAX3491CSD is a 3.3V-powered, full-duplex RS-485/RS-422 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 3.0V to 3.6V and supports data rates up to 10Mbps. The device features one driver and one receiver in a 14-pin SO package. Key electrical parameters include a typical supply current of 2.2mA, a shutdown current of 2nA, and a common-mode input voltage range from -7V to +12V. Driver outputs are protected against short circuits and thermal overload.

Feature Summary

Operates from a single 3.3V supply without requiring a charge pump
Interoperable with +5V logic levels
Includes low-current shutdown mode for power conservation
Features fail-safe receiver circuitry to guarantee high output when inputs are open

Applications

Telecommunications systems
Industrial-control local area networks
EMI-sensitive applications requiring reduced reflections

Procurement Notes

Verify the specific suffix 'CSD' corresponds to the 0°C to +70°C temperature range and 14-pin SO package. Confirm RoHS compliance status through official documentation. Ensure ordering details match the exact manufacturer part number to avoid functional discrepancies in interface compatibility.

Selection Notes

Select this component for full-duplex communication requirements where 10Mbps speed is necessary. Compare against half-duplex variants like the MAX3485 if bidirectional signaling on a single pair is sufficient. Consider the 14-pin package constraints versus the 8-pin options available in the same family for board space optimization.

Part Context

This device belongs to the MAX3483/MAX3485/MAX3486/MAX3488/MAX3490/MAX3491 series of low-power transceivers. It shares core architectural similarities with other members but is distinct as a full-duplex unit with dedicated enable pins and a 14-pin form factor.

Replacement Considerations

MAX3491ESD serves as a direct replacement offering an extended industrial temperature range (-40°C to +85°C) while maintaining identical pinout and electrical specifications.
