Overview
The P82B96TD/S911,118 is a bipolar integrated circuit (IC) produced by NXP USA Inc. It functions as a dual bidirectional bus buffer, designed to create a non-latching, bidirectional logic interface between the standard I2C-bus and various other bus configurations. This IC is capable of interfacing I2C-bus logic signals with buses having different voltage and current levels, such as the 350 μA SMBus, 3.3 V logic devices, and up to 15 V levels. This flexibility enhances noise immunity on longer bus lengths without restricting the normal I2C-bus protocols or clock speed.
