Add To BomPCA9540BDP General Description
The PCA9540BDP is a low-voltage 2-channel I2C-bus multiplexer/demultiplexer from Texas Instruments. It allows a master device to conveniently switch between multiple I2C buses or to isolate I2C devices on different buses. The PCA9540BDP features two bidirectional translating switches that can be controlled independently by the master device through the I2C-bus. Each channel has its own enable pin, allowing the master to activate or deactivate each bus segment as needed. This multiplexer/demultiplexer operates over a voltage range of 1.65V to 5.5V, making it suitable for a wide variety of low-power applications. It also has a high-speed mode (400 kHz) to support fast data transfer rates. The PCA9540BDP comes in a small 8-pin SOIC package, making it easy to integrate into existing designs. It has a low stand-by current consumption of 0.1 µA, making it ideal for battery-powered applications where power efficiency is crucial.
