PCA9541 2-to-1 I2C-bus master selector

The PCA9541 is a 2-to-1 I2C-bus master selector designed for high reliability dual master I2C-bus 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 .

PCA9541 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
