PCA9541PW03112

The NXP PCA9541PW,03112 is a 2-channel I2C-bus multiplexer with interrupt logic. It allows a master device to communicate with any of the two slave devices, each with a unique address, by multiplexing the SDA and SCL signals. The device supports standard and fast mode I2C-bus communication, and features an active-low interrupt output to indicate which channel has been selected.

Product details:

The PCA9541PW,03112 is a useful device for systems that require communication with multiple I2C-bus slave devices, particularly in battery-powered and space-constrained applications. Its interrupt logic simplifies system-level design by providing a convenient way to detect when a channel has been selected. The device is easy to use, and can be controlled via I2C-bus commands from a master device. The TSSOP16 package is small and requires minimal board space, making it ideal for compact designs.
