The MAX487CSA+ is a high-performance, low-power transceiver from Maxim Integrated designed for RS-485 and RS-422 communication. This device is ideal for applications requiring efficient data transmission over long distances or in noisy environments. It is particularly well-suited for industrial, network, and automation systems where reliable data communication is critical.

Key Features

• Low Quiescent Current: The MAX487CSA+ is designed to operate with a low quiescent current, making it suitable for power-sensitive applications.
• Slew-Rate Limited: This feature reduces electromagnetic interference (EMI) and reflections, ensuring data integrity over long cable runs.
• Half-Duplex Communication: The transceiver supports half-duplex communication, allowing for bidirectional communication on a single pair of wires.
• Extended Temperature Range: With an operating temperature range of -40°C to +85°C, it can reliably perform in various environments.
• Fail-Safe Receiver: The device guarantees a known output state if the input is open or shorted, enhancing robustness in communication systems.

Applications

• Industrial Control Systems
• Building Automation
• Network Equipment
• Security Systems

Technical Specifications

The MAX487CSA+ operates from a single 5V supply and features a 1/4-unit load receiver input impedance, which allows up to 128 transceivers on the bus. Its driver and receiver feature active-high and active-low enables, respectively, which can be externally connected to function as a direction control. The device's pinout is industry-standard, making it a drop-in replacement for many other RS-485/RS-422 transceivers.

Product Details

The MAX487CSA+ comes in an 8-pin SOIC package, providing a compact solution for space-constrained applications. Maxim Integrated's commitment to quality ensures that the MAX487CSA+ transceiver delivers reliable performance and robust communication in a variety of settings.
