Product Overview: MAX490MSA/PR+T

Maxim Integrated's MAX490MSA/PR+T is a high-performance, low-power, RS-485/RS-422 transceiver designed to facilitate robust communication in harsh industrial environments. This device is particularly well-suited for long-distance and high-speed applications where signal integrity and reliability are paramount.

Key Features

• Electrical Characteristics: The MAX490MSA/PR+T operates from a single 5V supply and features a quiescent current of only 300µA, making it an energy-efficient solution for power-sensitive applications. Its wide common-mode range of -7V to +12V ensures reliable data transmission even in the presence of ground potential differences.
• High-Speed Operation: With a data rate capability of up to 2.5Mbps, this transceiver can handle high-throughput applications, ensuring fast and efficient data exchange.
• Enhanced Protection: The device includes protection against ±15kV electrostatic discharge (ESD) shocks, as per the Human Body Model (HBM), which greatly enhances its robustness and longevity in challenging environments.
• Thermal Shutdown: An integrated thermal shutdown feature helps to prevent the device from overheating, ensuring that it operates within safe temperature ranges at all times.
• Fail-Safe Receiver: The receiver has a fail-safe feature that guarantees a logic-high output if the input is open circuit, shorted, or connected to a terminated transmission line with no signal present, thus preventing false signaling during idle periods.

Applications

The MAX490MSA/PR+T is designed to be versatile, catering to a wide range of industrial applications, including but not limited to:

• Industrial control systems
• Factory automation
• Building automation
• Networked security systems

Package and Quality

Maxim Integrated packages the MAX490MSA/PR+T in a space-saving 8-pin SOIC package, which is suitable for compact designs. The device is also available in tape and reel form (suffix 'T'), facilitating efficient handling and assembly processes in high-volume production environments. Maxim Integrated is committed to maintaining high-quality standards, and the MAX490MSA/PR+T is no exception, offering reliable performance for critical communication tasks.

With its combination of speed, efficiency, and robustness, the MAX490MSA/PR+T from Maxim Integrated stands out as a top choice for developers looking to implement RS-485/RS-422 communication protocols in their systems.
