The MAX4885ETJ+ is an RS-485/RS-422 transceiver that provides full-duplex communication over long distances and high noise environments. Manufactured by Maxim Integrated, it offers several key features that make it suitable for industrial automation, automotive, and other applications.
Firstly, the MAX4885ETJ+ supports a wide common-mode range of -7V to +12V, which allows it to operate in noisy and harsh industrial environments. This robustness ensures reliable transmission of data over long distances by minimizing the effects of common-mode voltage differences between devices.
The device is compliant with both RS-485 and RS-422 standards, providing compatibility with a wide range of existing industrial communication systems. With RS-485, the transceiver can support up to 32 transceivers connected to a bus. It also supports full-duplex communication, enabling simultaneous transmission and reception, which is essential for systems requiring bidirectional data transfer.
The transceiver offers a high data rate of up to 20Mbps, enabling fast and efficient communication between devices. This high-speed capability makes it suitable for applications that require real-time data exchange.
Another notable feature of the MAX4885ETJ+ is its low power consumption. It features a shutdown mode that reduces the supply current to less than 1
