The MAX483EPA+ is a low-power, slew-rate-limited transceiver from Maxim Integrated, designed for RS-485 and RS-422 communication. This transceiver is a reliable solution for applications requiring moderate data rates and long cable lengths. Its controlled slew-rate limiting minimizes electromagnetic interference (EMI) and reduces reflections caused by improperly terminated cables, making it ideal for industrial environments.

Key Features

• Low Power Consumption: The MAX483EPA+ operates with a very low supply current, typically 300µA, making it suitable for power-sensitive applications.
• Half-Duplex Interface: It supports bidirectional communication on a single twisted-pair, allowing for the transmission and reception of data in a half-duplex manner.
• Slew-Rate Limited: The device's slew-rate limitation ensures reduced EMI and less signal reflection, which is crucial for maintaining signal integrity over long cable runs.
• Wide Voltage Range: The MAX483EPA+ operates from a single 5V supply, with a voltage range of 4.75V to 5.25V, providing flexibility in various power supply scenarios.
• Extended Temperature Range: With an operating temperature range of -40°C to +85°C, it is well-suited for harsh industrial environments.
• Fail-Safe Receiver: The receiver remains in a high-impedance state when the bus is idle, shorted, or open, ensuring a fail-safe operation.

Applications

The MAX483EPA+ is designed for multipoint data transmission standard in various applications such as:

• Industrial Control Systems
• Building Automation
• Factory Automation
• Networked Security Stations
• Remote Sensors
