== Summary ==
8-channel I2C switch enabling multiple I2C devices to share a single bus with individual channel selection.

== Description ==
The TCA9548A component is an I2C switch that allows up to 8 I2C devices to share a single I2C bus. Each channel can be individually selected and controlled, preventing address conflicts and enabling efficient bus management. The switch features low standby current, power-on reset function, and supports both standard and fast mode I2C protocols. Typical applications include multi-sensor systems, display multiplexing, and complex I2C bus architectures.
