3 Description

The P82B715 is a device for buffering highlycapacitive

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.
