The Texas Instruments PCA9543APWR is a versatile 2-channel I2C and SMBus switch that also provides voltage translation capabilities. It supports a wide operating supply voltage range from 2.3V to 5.5V, making it suitable for various system designs. The device features two address pins, allowing up to four PCA9543A devices on the I2C bus, and offers channel selection via the I2C bus in any combination.
Key electrical characteristics include a maximum clock frequency of 400kHz and an operating temperature range of -40°C to 85°C. The switch is designed for bidirectional translation, supporting voltage levels between 1.8V, 2.5V, 3.3V, and 5V buses. It includes features such as an interrupt pin, a reset pin, and 5.5V tolerant inputs.
Packaged in a 14-TSSOP, the PCA9543APWR is designed for surface mount applications. Its design ensures no glitch on power-up and supports hot insertion. This component is ideal for applications requiring multiple I2C buses or voltage level shifting between different bus segments.
