Description
- The PCA9547PW is a 8-channel I²C-bus Multiplexer with reset. The PCA9547 is an octal bidirectional translating multiplexer controlled by the I²C-bus. The SCL/SDA upstream pair fans out to eight downstream pairs or channels. Only one SCx/SDx channel can be selected at a time, determined by the contents of the programmable control register. The device powers up with channel 0 connected, allowing immediate communication between the master and downstream devices on that channel. An active LOW reset input allows the PCA9547 to recover from a situation where one of the downstream I²C-buses is stuck in a low state. Pulling the RESET pin low resets the I²C-bus state machine causing all the channels to be deselected, except channel 0 so that the master can regain control of the bus. The pass gates of the multiplexers are constructed such that the VDD pin can be used to limit the maximum high voltage which will be passed by the PCA9547.
- 1-of-8 Bidirectional translating multiplexer
