Overview
The P82B96TD/S900,118 is a dual bidirectional bus buffer integrated circuit (IC) manufactured by NXP USA Inc. This bipolar IC is designed to create a non-latching, bidirectional logic interface between the standard I2C-bus and various other bus configurations. It enables the interfacing of I2C-bus logic signals to buses with different voltage and current levels, such as the 350 μA SMBus, 3.3 V logic devices, and 15 V levels, without restricting the normal I2C-bus protocols or clock speed.
