NXP PCA9516AD I²C-Bus Repeater

The NXP PCA9516AD is a sophisticated integrated circuit designed to facilitate robust I²C-bus communication in complex environments. This I²C-bus repeater allows for the extension of the I²C-bus by buffering both the data (SDA) and the clock (SCL) lines, enabling the connection of multiple devices over extended distances.

Key Features

• 5-Channel Hub: The PCA9516AD integrates five bidirectional channels that can be used to create a branching I²C-bus network.
• Voltage Level Translation: It operates over a wide supply voltage range (2.3V to 5.5V) and can translate between different voltage levels, making it suitable for multi-voltage systems.
• High Noise Immunity: With built-in hot-swap capabilities, it ensures a high level of noise immunity and prevents glitches on the I²C-bus during live insertion and removal of boards.
• Low Standby Current: The device's low standby current is a boon for power-sensitive applications.

Applications

The PCA9516AD is ideal for a variety of applications where I²C-bus signal integrity is crucial. It is commonly used in:

• Server and telecom infrastructure
• Industrial control systems
• Consumer electronics
• Automotive networks

Package and Quality

Encased in a compact 16-pin TSSOP package, the PCA9516AD is designed for space-constrained applications. It is compliant with the stringent quality standards required for industrial and automotive applications, ensuring reliable performance in diverse operating conditions.
