MAX3491ECSD

Overview

The MAX3491ECSD is a +3.3V, low-power transceiver for RS-485 and RS-422 communications, featuring ±15kV ESD protection. It contains one driver and one receiver with a guaranteed data rate of 12Mbps. The device operates from a single +3.3V supply without a charge pump and is interoperable with +5V logic. It supports full-duplex communication and includes a 2nA low-current shutdown mode. The EC suffix indicates an extended commercial temperature range of 0°C to +70°C, housed in a 14-pin SO package.

Feature Summary

Full-duplex communication capability with independent driver and receiver control
Enhanced electrostatic discharge (ESD) protection on all I/O pins
Low-power shutdown mode with minimal supply current consumption
Driver short-circuit current limiting and thermal shutdown protection

Applications

Telecommunications systems
Industrial-control local area networks
Transceivers for EMI-sensitive applications
Integrated services digital networks
Packet switching environments

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and temperature grade. Ensure compatibility with system voltage levels and interface requirements before procurement. Cross-reference part numbers with authorized distributors to confirm authenticity and availability status.

Selection Notes

Select this component for applications requiring full-duplex RS-485 or RS-422 communication at speeds up to 12Mbps. It is suitable for designs needing robust ESD protection and low power consumption in a compact surface-mount package. Consider the 0°C to +70°C operating range when evaluating environmental constraints.

Part Context

The MAX3491E belongs to the MAX3483E family of 3.3V transceivers designed for RS-485 and RS-422 standards. Unlike half-duplex variants in the series, the MAX3491E provides full-duplex operation. It shares common features such as low-power shutdown and enhanced ESD protection with other members like the MAX3485E and MAX3490E.
