PCA9548ADBR
Texas InstrumentsPCA9548ADBR from Texas Instruments is a Integrated Circuit 8-channel 2.3- to 5.5-V I2C/SMBus switch with reset & voltage translation - I2C & I3C switches & multiplexers. The PCA9548A device has eight bidirectional translating switches that can be controlled through the I 2 C bus. The SCL/SDA upstream pair fans out to 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 I 2 C 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 I 2 C/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 I 2 C buses get stuck in a low state. The pass gates of the switches are constructed so that the V CC pin can be used to limit the maximum high voltage, which is passed by the PCA9548A. This allows the use of different bus voltages on each pair, so that 1.8-V, 2.5-V or 3.3-V parts can communicate with 5-V parts, without any additional protection. External pull-up resistors pull the bus up to the desired voltage level for each channel. All I/O pins are 5-V tolerant.
