The P82B715 is a device for buffering highly-capacitive I2C bus systems, and it supports bidirectional data transfer through the I2C bus. The P82B715 buffers both the serial data (SDA) and serial clock (SCL) signals on the I2C bus and allows for extension of the I2C bus, while retaining all the operating modes and features of the I2C system.
