Home Bus System (HBS) Compatible Transceiver

The MAX22288 Home Bus System (HBS) compatible transceiver 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.

The MAX22288 provides robust communication by using dynamic cable termination that improves the signal quality with longer cables and higher data rates. The device data outputs AIO/BIO do not load the bus when the MAX22288 is not powered. The MAX22288 supports passing data with speed up to 200kbps.

The MAX22288 features adjustable receiver thresholds and driver slew rates that allow the MAX22288 to be used in a wide variety of systems. Integrated protection ensures robust communication in harsh industrial environments.

The MAX22288 is pin-to-pin compatible with the MAX22088, the Home Bus System (HBS) Compatible Transceiver with Active Inductor. The MAX22288 is recommended for use in an HBS system where an external power supply is typically available.

The MAX22288 is specified for operation over the -40°C to +125° C temperature range and is available in a compact 24-pin 4mm x 4mm TQFN package.
