MAX22288ATG+

MAX22288ATG+ is a home bus system (HBS) compatible transceiver that can be used in the home bus system, where data and power are passed on a single pair of wires while minimizing the need for external components. It provides robust communication by using dynamic cable termination that improves signal quality with longer cables and higher data rates. This device data outputs AIO/BIO do not load the bus when the device is not powered. It supports passing data with speeds up to 200Kbps. It features adjustable receiver thresholds and driver slew rates that allow the device to be used in a wide variety of systems. Integrated protection ensures robust communication in harsh industrial environments. It is used in applications such as HVAC, building controllers, industrial IoT.
