PCA9641 2-channel I2C-bus master arbiter

PCA9641 Description

PCA9641 2-channel I2C-bus master arbiter Rev.2.1 * 27 October 2015 Product data sheet 1.General .
The PCA9641 is a 2-to-1 I2C master demultiplexer with an arbiter function.

PCA9641 Features

* 2-to-1 bidirectional master selector
* Channel selection via I2C-bus
* I2C-bus interface logic; compatible with SMBus standards
* 2 active LOW interrupt outputs to master controllers
* Active LOW reset input
* Software reset
* Four address pins allowing up to 112 differ

PCA9641 Applications

* where correct system operation is required, even when two I2C-bus masters issue their commands at the same time. The arbiter will select a winner and let it work uninterrupted, and the losing master will take control of the I2C-bus after the winner has finished. The arbiter also allows for queued re
