The NXP PA9546A is a state-of-the-art, 4-channel I²C-bus switch with reset functionality. This advanced integrated circuit (IC) is designed to enhance the capabilities of the I²C-bus by enabling communication with multiple I²C devices that share the same bus. It is particularly useful in complex systems where multiple ICs need to be accessed independently without interference.

Key Features

• Multi-Channel Interface: The PA9546A features four bidirectional translating switches that can connect to four separate slave or master devices.
• Channel Selection: Each switch can be controlled via the I²C-bus, allowing individual channel selection for device communication.
• High Noise Immunity: With built-in noise-filtering capability, the PA9546A ensures reliable operation even in electrically noisy environments.
• Low Standby Current: The device is designed for energy efficiency, with a low standby current that minimizes power consumption when not in active use.
• Hardware Reset: A hardware reset input is available, which resets the I²C-bus state machine, aiding in system recovery and initialization.
