Product Details


Maxim Integrated’s MAX3490EESA+T: The RS-485/RS-422 Transceiver

The MAX3490EESA+T is a high-performance, half-duplex transceiver from Maxim Integrated, designed to facilitate robust communication in industrial, network, and automation systems. This transceiver is specifically tailored for RS-485 and RS-422 communication protocols, which are widely used for serial data transmission over long distances and in electrically noisy environments.

Encased in a compact 8-pin NSOIC package, the MAX3490EESA+T operates over a wide 3.3V supply voltage range, making it versatile for various applications. Its low-power consumption and extended temperature range from -40°C to +85°C ensure reliable performance in harsh industrial conditions. The device also integrates a slew-rate-limited driver, which minimizes electromagnetic interference (EMI) and reduces reflections caused by improperly terminated cables, thus enhancing data integrity and transmission reliability.

With its ability to drive up to 32 transceivers on the bus, the MAX3490EESA+T is an excellent choice for networked devices in a multi-point communication system. The transceiver’s high-speed operation of up to 10Mbps is well-suited for fast data communication needs, while its fail-safe receiver feature guarantees a known output state when inputs are left open, shorted, or idle. This is critical for ensuring system safety and preventing data corruption during line faults or inactive periods.

The MAX3490EESA+T also boasts robust electrostatic discharge (ESD) protection, safeguarding the device against the effects of static electricity and enhancing its durability in the field. Moreover, its thermal shutdown feature prevents damage from overheating, thus ensuring long-term reliability.

For designers and engineers looking for a reliable solution for differential data transmission, the MAX3490EESA+T from Maxim Integrated stands out as a top choice. Its combination of high-speed communication, robust protection features, and low-power operation makes it an ideal component for designing efficient and durable communication systems in demanding industrial environments.

Whether it’s for factory automation, HVAC systems, or any other application requiring dependable serial communication, the MAX3490EESA+T delivers performance and quality that professionals can trust.
