Maxim Integrated's MAX1486EUB+ RS-485/RS-422 Transceiver

The MAX1486EUB+ is a high-performance, low-power transceiver for RS-485 and RS-422 communication, designed by Maxim Integrated. This device is specifically engineered to operate in half-duplex communication systems that require high data rates, robust noise immunity, and long cable runs. With its compact µMAX package, the MAX1486EUB+ is an ideal solution for space-constrained applications.

Key Features

• High-Speed Operation: The MAX1486EUB+ supports data rates up to 2.5Mbps, making it suitable for high-speed data communication in industrial, telecom, and networking applications.
• Reduced Power Consumption: It operates from a single 5V supply with a low quiescent current of only 300µA, which is ideal for power-sensitive designs.
• Enhanced Protection: The device includes integrated protection features such as ±15kV ESD protection on the transceiver's input and output pins, safeguarding the device against electrostatic discharges and enhancing system reliability.
• Extended Temperature Range: The MAX1486EUB+ is designed to perform reliably in extreme environments with an operating temperature range of -40°C to +85°C.
• True Fail-Safe Receiver: The receiver has a true fail-safe feature that ensures a logic-high receiver output if the input is open-circuit, shorted, or connected to a terminated transmission line with all drivers disabled.
• Thermal Shutdown: An integrated thermal shutdown feature protects the device from damage due to excessive power dissipation.

Applications

The MAX1486EUB+ is versatile and can be used in a wide range of applications, including:

• Industrial Control Systems
• Building Automation
• Network Equipment
• Security Systems
• Point-of-Sale (POS) Terminals

Package and Availability
