NXP PCA9541APW03118 I2C bus selector
The PCA9541A is a high-reliability, dual master I2C-bus selector with interrupt logic and reset. Designed for applications requiring system operation continuity even if one master fails or is removed, it connects two separate I2C-buses to shared slave devices. Features include channel control via I2C, bus initialization, interrupt signaling, voltage level translation up to 5V, and support for hot insertion. It operates within a supply voltage range of 2.3V to 5.5V, with options for various packages like SO16, TSSOP16, HVQFN16, and offers robust ESD protection and low standby current.
