Overview
The P82B715PN,112 is an I2C-bus extender IC produced by NXP USA Inc. This bipolar integrated circuit is designed to extend the practical separation distance between components on the I2C-bus by buffering both the data (SDA) and the clock (SCL) lines. It retains all the operating modes and features of the I2C-bus, allowing for increased communication distances and higher system capacitance loads.
