TCA9548ARGER, 8-канальный коммутатор I2C со сбросом VQFN-24 (4x4)

TCA9548A 8-Channel I2C Switch
Texas Instruments TCA9548A 8-Channel I 2 C Switch 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 SCn/SDn 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 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 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 one of the downstream I 2 C buses get stuck in a low state.
