The P82B96 series Signal Buffers from Texas Instruments is a bus buffer that enables bidirectional data transfer between an I2C bus and other bus configurations with different voltage and current levels. It is designed to support longer cables and allow for more devices per I2C bus by isolating bus capacitance. The P82B96 can provide galvanic isolation or use balanced transmission lines for communication. It features separate directional signals for transmitting and receiving data.
It is important to note that there are restrictions on interconnecting certain pins of the P82B96. The Sx/Sy side is intended for I2C logic voltage levels, while the Tx/Rx and Ty/Ry pins can be interconnected with other P82B96 devices. However, the Sx pins of different devices should never be linked to avoid induced noise and to support all I2C operating modes.
