What is MAX485?

The MAX485 is a low-power and high-speed RS-485/RS-422 transceiver that enables reliable, long-distance communication. It is widely used for industrial automation, data acquisition, and communication systems that require robust performance over extended distances. The following are some key features for your reference:

High Speed: Support data rates up to 2.5 Mbps, enabling fast and efficient communication in the serial circuit.
Long-Distance Communication: Designed for long-range communication, the MAX485 can maintain signal integrity over distances up to 1200 meters (4000 feet).
RS-485/RS-422 Compatibility: The MAX485 supports both RS-485 and RS-422 communication protocols, providing flexibility for different types of serial device connections.
Low Supply Voltage: Operate at a low supply voltage, generally 5V, which simplifies power requirements and enhances compatibility with a variety of power sources.
Differential Signaling: The MAX485 uses differential signaling to reduce noise, enhance data integrity, and improve communication reliability.
