MAX485 transceiver

The MAX485 is a low-power transceiver for RS-485 and RS-422 communication. It features a half-duplex communication mode, which means that the transceiver can either transmit or receive data at a given time, but not both simultaneously. This transceiver is designed to operate with a single 5V power supply and provides robust performance for high-speed data transmission over long distances. The MAX485 is ideal for applications requiring minimal power consumption and reliable data transfer in electrically noisy environments.
