The NXP P82B96DP,118 is a versatile I²C bus buffer that significantly enhances the capabilities and performance of I²C bus systems. Designed to provide bidirectional buffering for both the data (SDA) and the clock (SCL) lines, this device allows for the extension of the I²C bus communication over longer distances and supports higher capacitance buses than what would be possible with a standard I²C interface.

Key Features

• Extended Range: The P82B96DP,118 allows I²C communication to be extended up to 3000 feet (900 meters), vastly increasing the range over which devices can communicate.
• Increased Load Capacity: With the ability to support bus capacitance up to 4000 pF, this buffer enables more devices to be connected on the same bus without compromising signal integrity.
• Compatibility: It is fully compatible with I²C standard modes and can be used with standard I²C devices as well as other bus buffer devices.
• Low Standby Current: The P82B96DP,118 features a low standby current, making it suitable for power-sensitive applications.
• Noise Filtering: This device includes noise filtering on the SCL/SDA inputs, ensuring robust performance in noisy environments.
• Voltage Level Translation: It can also provide level shifting for the I²C bus which allows for different voltage levels to be interfaced on the same bus.

Applications

The P82B96DP,118 is ideal for various applications, including:

• Industrial control systems
• Automotive networks
• Building automation
• Extended range sensor networks
• Advanced consumer electronics
