NXP PCA9541ABS01118 2-1 I2C Bus Selector

The PCA9541 is a high-reliability, 2-to-1 I2C-bus master selector with interrupt logic and reset functionality, designed for dual master systems. It allows control of downstream I2C devices by either master, even if one fails or is removed. Features include bus recovery, voltage level translation between different bus voltages, multiple package options, and active low reset and interrupt inputs/outputs. Ideal for applications requiring constant system operation, resource sharing, and bus initialization without hardware reset, it enhances reliability and system robustness.
