P82B96 Dual Bidirectional Bus Buffer NXP Semiconductors P82B96 Dual Bidirectional Bus Buffer is a bipolar IC that creates a non-latching, bidirectional, logic interface between the normal I²C bus and a range of other bus configurations. The P82B96 dual bidirectional bus buffer can have different voltages and current levels with interface I²C bus logic signals to similar buses. This P82B96 dual bidirectional bus buffer achieves this interface without any restrictions on the normal I²C bus protocols or clock speed. The dual bidirectional bus buffer IC adds minimal loading to the I²C bus node and loadings of the new bus or remote I²C bus nodes are not transmitted or transformed to the local node.
