Maxim Integrated MAX3490ESA+T

The MAX3490ESA+T from Maxim Integrated is a high-performance RS-422/RS-485 transceiver designed for reliable data communication in industrial and embedded systems. It operates from a single 3.3V power supply without the need for a charge pump, while remaining fully compatible with 5V logic levels. The device supports full-duplex communication and features low propagation skew of up to 8ns, ensuring accurate signal timing in high-speed data transmission environments. With a wide common-mode input voltage range from –7V to +12V, it maintains stable operation even in electrically noisy conditions.

Housed in a compact 8-pin SOIC package, the MAX3490ESA+T allows up to 32 transceivers to share the same bus, making it well suited for multi-node networks. It also integrates built-in current limiting and thermal shutdown to protect against driver overload and overheating, enhancing system reliability. These features make the device ideal for applications such as industrial automation, building control systems, communication interfaces, and instrumentation equipment where robust, low-power, and dependable RS-422/RS-485 communication is required.
