The P82B96PW is a dual bidirectional Bus Buffer that supports bidirectional data transfer between an I²C bus and a range of other bus configurations with different voltage and current levels. One of the advantages of the P82B96 is that it supports longer cables/traces and allows for more devices per I²C bus because it can isolate bus capacitance such that the total loading of the new bus or remote I²C nodes are not apparent to other I²C buses. The restrictions on the number of I²C device in a system due to capacitance or the physical separation between the devices are greatly improved. The device is able to provide galvanic isolation or use balanced transmission lines, because separate directional Tx and Rx signals are provided. The Tx and Rx signals may be connected directly, to provide an bidirectional signal line with I²C properties. Likewise, the Ty and Ry signals may also be connected together to provide an bidirectional signal line with I²C properties.
