Description: 2-to-1 I2C-bus master selector

Features

* 2-to-1 bidirectional master selector
* I2C-bus interface logic; compatible with SMBus standards
* PCA9541/01 powers up with Channel 0 selected
* PCA9541/03 powers up with no channel selected and either master can take control of the bus
* Active LOW interrupt input
* 2 acti

Applications

* where system operation is required, even when one master fails or the controller card is removed for maintenance. The two masters (for example, primary and back-up) are located on separate I2C-buses that connect to the same downstream I2C-bus slave devices. I2C-bus commands are sent by either I2C-bu
