Maxim Integrated MAX487EEPA Overview

The MAX487EEPA is a low-power transceiver for RS-485 and RS-422 communication from Maxim Integrated. It is designed to provide reliable, high-speed data transmission for industrial, network, and automation applications where a differential communication is required. The MAX487EEPA operates with a single 5V power supply and features a quiescent current that allows for energy-efficient operation, making it suitable for battery-powered and power-sensitive systems.

Key Features

• Electrical Interface: The device supports RS-485/RS-422 communication protocols, ensuring compatibility with a wide range of industrial communication systems.
• Half-Duplex Operation: The MAX487EEPA is designed for half-duplex communication, allowing for bidirectional communication over a single pair of wires.
• Low Quiescent Current: With a low supply current of only 300µA, the device is optimized for low-power applications.
• Extended Temperature Range: The transceiver is operational over a temperature range of -40°C to +85°C, making it reliable in various harsh environments.
• Integrated Protection: The device features fail-safe circuitry that ensures a logic-high receiver output when the receiver inputs are open or shorted, or when they are connected to a terminated transmission line with all drivers disabled.
• High Speed: The MAX487EEPA can achieve data rates up to 2.5Mbps, allowing for efficient data transfer in time-sensitive applications.
• Pin-Compatible Upgrades: This device is available in an 8-pin DIP package and is pin-compatible with the industry-standard MAX485 and SN75176.
• Integrated Receiver/Differential Driver: The device includes a differential line driver and a differential input line receiver.
