PCA9546ADR TI Switches, Multiplexers, Demultiplexers

PCA9546ADR is a 4-channel I²C bus multiplexer with reset function in SOIC package from Texas Instruments for general I²C expansion. It operates at 2.3 V to 5.5 V, supporting 100 kHz and 400 kHz I²C bus speeds, with four individually selectable channels. Low on-resistance and low crosstalk avoid signal degradation, while hardware reset, hot-swap capability and ESD protection improve system robustness. The device works across -40 °C to 85 °C. It is packaged in a 16-SOIC for easy assembly. It is widely used in general embedded systems, sensor arrays, consumer electronics, industrial modules and medium-scale multi-device I²C bus expansion applications.
