The NXP PCA9547 is a 2-bit, 8-channel I2C translating multiplexer, enabling bidirectional voltage translation for the I2C and SMBus communication protocols. This device facilitates the connection of low-voltage microcontrollers to higher-voltage I2C bus devices, or vice versa. It operates across two distinct supply voltage ranges: 2.3V to 3.6V and 4.5V to 5.5V, offering significant flexibility in mixed-voltage system designs. The PCA9547 features active-low reset and interrupt outputs, and supports standard, fast, and fast-mode Plus I2C speeds. Its low operating current and robust ESD protection make it suitable for applications in industrial automation, consumer electronics, and automotive systems where reliable inter-device communication across voltage domains is critical. Supplied in a 24-TSSOP package for surface mounting.
