TCA9548A Low-Voltage 8-Channel I 2C eight bidirectional translating switches
Last items in stock
$0.00
The TCA9548A device has eight bidirectional translating switches that can be controlled through the I 2C 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 2C 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.
