DESCRIPTION/ORDERING INFORMATION
The P82B96 is a bipolar device that supports bidirectional data transfer between the normal I2C bus and a range
of other bus configurations with different voltage and current levels. It can function as the interface without any
limitations on the normal I2C operation and clock speed.
