Overview
The PCA9541APW/03/112 is a 2-channel I2C-bus multiplexer produced by NXP USA Inc. This integrated circuit is designed to allow multiple I2C-bus compatible devices to share the same I2C-bus, thereby simplifying the design and reducing the number of I2C-bus lines in a system. The device is particularly useful in applications where multiple sensors, EEPROMs, or other I2C devices need to be connected to a single microcontroller.
