Product Description

The TCA9548APWR is an eight-channel Bidirectional Translating Switch can be controlled through the I²C bus. The SCL/SDA upstream pair fans out to eight downstream pairs or channels. Any individual SCn/SDn channel or combination of channels can be selected, determined by the contents of the programmable control register. The system master can reset the TCA9548A 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. The pass gates of the switches are constructed so that the VCC pin can be used to limit the maximum high voltage, which is passed by the TCA9548A. Limiting the maximum high voltage allows the use of different bus voltages on each pair, so that 1.8 or 2.5 or 3.3V parts can communicate with 5V parts, without any additional protection.
