i2c pca9548

I2C PCA9548 is a multiplexer/demultiplexer IC (Integrated Circuit) that allows multiple I2C devices to share the same I2C bus. It provides a way to expand the number of available I2C addresses and enables communication with multiple devices using a single I2C bus.

The PCA9548 has 8 channels, each of which can be independently controlled to connect or disconnect a specific I2C device from the bus. This allows for efficient management of multiple I2C devices, especially in situations where there are limited I2C addresses available.

To use the PCA9548, you need to communicate with it over the I2C bus using the appropriate I2C commands. By selecting the desired channel, you can control which I2C device is connected to the bus and communicate with it.

Some key features of the PCA9548 include:

1. 8 channels for connecting multiple I2C devices.
2. Individual channel control for enabling/disabling specific devices.
3. Low RDS(on) switches for minimal signal distortion.
4. Supports I2C bus speeds up to 400 kHz.
5. Compatible with both 3.3V and 5V systems.
