Maxim Integrated MAX1487CPA Overview

The MAX1487CPA is a high-performance, low-power, RS-485/RS-422 transceiver designed by Maxim Integrated to facilitate robust communication in electrically noisy environments. This integrated circuit is specifically engineered to operate in half-duplex communication systems that require the transmission and reception of data over long distances or in challenging electrical conditions.

Key Features

• Electrical Interface: The device is compliant with the EIA/TIA-485 communication standard, ensuring compatibility with a wide range of industrial applications.
• Driver/Receiver Enable: It features independent driver and receiver enable functions, allowing for greater control over the transceiver's operation.
• Speed and Distance: With a data rate of up to 2.5Mbps, the MAX1487CPA can handle high-speed data transmission. It is also capable of driving long cable lengths, making it ideal for distributed networks.
• Power Efficiency: The device operates from a single 5V supply, consuming only 300μA of supply current, which is significantly lower than other transceivers, thus making it suitable for power-sensitive applications.
• Protection: It includes 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.
• Thermal Shutdown: The MAX1487CPA is equipped with thermal shutdown protection to prevent damage from excessive power dissipation.

Applications

The robustness and versatility of the MAX1487CPA make it an excellent choice for various applications, including:

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

Package and Quality
