P82B715P General Description

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.

For all available packages, see the orderable addendum at the end of the data sheet.
