TCA9548ARGER Description

Short technical summary and product information.

The TCA9548ARGER is an 8-channel I2C bus switch from Texas Instruments designed for multiplexing I2C bus signals. It features a single 1 x 8:1 circuit configuration, allowing one I2C master to communicate with up to eight slave devices. The device operates from a single supply voltage ranging from 1.65V to 5.5V, making it suitable for low-voltage systems. It supports a maximum switching frequency of 400kHz, compatible with standard I2C fast-mode operation.

 

The TCA9548ARGER includes ESD protection rated at ±2000V for the human-body model, 200V for the machine model, and ±1000V for the charged-device model. It also features latch-up performance exceeding 100mA. The device is housed in a 24-VQFN (4x4) package with an exposed pad for surface-mount assembly. It is specified for an operating temperature range of -40°C to 85°C, suitable for industrial environments.
