DESCRIPTION/ORDERING INFORMATION
The P82B715 is a bipolar device intended for I²C bus systems applications and supports bidirectional data
transfer via 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.
