Maxim Integrated MAX488EESA+T RS-485/RS-422 Transceiver

The MAX488EESA+T from Maxim Integrated is a low-power, slew-rate-limited transceiver designed for RS-485 and RS-422 communication. This device is particularly well-suited for long-distance and noisy environments, commonly found in industrial applications. The MAX488EESA+T operates from a single 5V supply and features a quarter-unit-load receiver input impedance, allowing up to 128 transceivers on the bus.

Key Features

• Slew-Rate Limited: The MAX488EESA+T ensures reduced EMI and reflections, making it ideal for applications where data integrity and transmission distance are critical.
• Low Power Consumption: With its low-power shutdown mode, this transceiver minimizes power usage when not in active operation, thus conserving energy and extending the life of battery-powered devices.
• High Receiver Input Impedance: The device supports up to 128 transceivers on the bus, which is significantly higher than standard 32-unit loads, providing greater network expandability.
• Fail-Safe Receiver: The MAX488EESA+T ensures a logic-high receiver output when the input is open, shorted, or idle, thereby preventing false signals in the absence of input data.

Applications

The MAX488EESA+T is versatile and can be used in a variety of applications, including:

• Industrial Control Systems
• Building Automation
• Networked Security Systems
• Data Collection Devices
• Remote Sensors

Packaging and Availability

This transceiver comes in a narrow 8-pin SO package, designated by the EESA suffix, and is supplied in tape and reel form (indicated by the +T), which is suitable for automated assembly processes. The MAX488EESA+T is part of Maxim Integrated's commitment to providing robust and reliable communication solutions for complex industrial environments.

With its combination of features, the MAX488EESA+T transceiver is an excellent choice for designers looking for a dependable and efficient solution for RS-485/RS-422 communication networks.
