MAX490MJA - Low-Power, Slew-Rate-Limited RS-485/RS-422 Transceivers

The MAX490MJA is a high-performance transceiver from Maxim Integrated, designed for RS-485 and RS-422 communication networks. This device is particularly suited for long-distance and high-speed data communication applications where low power consumption and minimal electromagnetic interference (EMI) are crucial.

Key Features

• Slew-Rate Limited: The MAX490MJA features a controlled slew rate which limits the rate of change in the signal, reducing EMI and allowing error-free data transmission over longer cable lengths.
• Low Power: With its low-power operation, the device is ideal for energy-sensitive applications, making it a popular choice for portable and remote systems.
• Half-Duplex Communication: The transceiver supports half-duplex communication, allowing bidirectional communication on a single pair of wires, which helps in reducing the overall system cost and complexity.
• Extended Temperature Range: The MAX490MJA operates over a wide temperature range, making it suitable for industrial environments and outdoor applications.
• High Data Rates: Despite its low-power design, the device supports data rates up to 2.5Mbps, which is more than adequate for many control and automation tasks.
• Fail-Safe Receiver: The receiver inputs have a fail-safe feature that guarantees a known output state if the inputs are open or shorted.

Applications

The MAX490MJA is versatile and can be used in a variety of applications, including:

• Industrial control systems
