Overview
The P82B715TD,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. This allows for longer communication distances and increased system capacitance, making it a valuable component in various electronic systems.
