Introducing the NXP FBL2033B - A Robust I²C-bus Buffer

The NXP FBL2033B is a high-performance, dual bidirectional I²C-bus buffer that is designed to provide the necessary interfacing in a multi-voltage and hot-swappable card environment. This device is an essential component for system designers looking to enhance the capabilities of I²C-bus communication in complex systems.

Key Features

• Hot Swap Capability: The FBL2033B is designed to support live insertion and removal of cards without disrupting the operation of the backplane, making it ideal for server, telecom, and networking applications.
• Level Shifting: With the ability to interface between different logic levels, this buffer can connect devices that operate on different voltage levels, simplifying system design and enhancing flexibility.
• Enhanced Signal Integrity: The FBL2033B improves signal integrity by providing a stronger drive capability, which is particularly useful in applications where long bus lines are present.
• Bus Capacitance Buffering: It allows more devices to be connected on the I²C-bus by buffering the capacitance, thereby extending the bus loading limit.

Applications

The FBL2033B is suitable for a wide range of applications, including:

• Server and Storage Systems
• Networking Equipment
• Telecommunications Infrastructure
• Industrial Control Systems

Technical Specifications

The NXP FBL2033B operates over a wide temperature range and features two separate sinking outputs for interrupt and reset with active LOW. It also includes an active HIGH enable input, which can be used to control the buffer's operation.
