The PCA9548A device has eight bidirectional translating switches that can be controlled through the I2C bus. The SCL/SDA upstream pair fans out to I2C or SMBus Master SDA (processor) eight downstream pairs, or channels. Any individual SCx/SDx channel or combination of channels can be selected, determined by the contents of the programmable control register. These downstream channels can be used to resolve I2C slave address conflicts. For example, if eight identical digital temperature sensors are needed in the application, one sensor can be connected at each channel: 0-7. The system master can reset the PCA9548A in the event of a time-out or other improper operation by asserting a low in the RESET input. Similarly, the power-on reset deselects all channels and initializes the I2C/SMBus state machine. Asserting RESET causes the same reset and initialization to occur without powering down the part. This allows recovery should once of the downstream I2C buses get stuck in a low state. 




Applications
• Servers
• Routers (Telecom Switching Equipment)
• Factory Automation
• Products With I2C Slave Address Conflicts (For Example, Multiple, Identical Temp Sensors)
