The PCA9548A is an 8-channel bidirectional I2C switch designed to resolve I2C slave address conflicts, allowing multiple identical devices to be connected to a single I2C bus. It features a low voltage operation range of 2.3 V to 5.5 V and supports voltage-level translation between 1.8 V, 2.5 V, 3.3 V, and 5 V buses. The device includes an active-low reset input, enabling system recovery from time-outs or improper operations without needing to power down. It can be configured to allow the selection of any combination of channels via the I2C bus, and it supports hot insertion with low standby current. The PCA9548A is suitable for applications in servers, routers, and factory automation, and it is available in multiple package types, including 24-pin VQFN. ESD protection ratings exceed industry standards, ensuring reliability in various environments.
