NXP PCA9540BDPQ900J I2C Multiplexer
The PCA9540B is a 2-channel I²C-bus multiplexer that allows voltage level translation between different bus voltages such as 1.8 V, 2.5 V, 3.3 V, and 5 V. It features a bidirectional, controlled via I2C, with channels that can be independently selected through a control register. The device supports hot insertion, low standby current, and wide power supply range from 2.3 V to 5.5 V. Its pass gates allow limiting voltage passed, making it suitable for mixed-voltage systems with various protection needs. The PCA9540B is ideal for complex multi-voltage I²C applications, ensuring reliable signal switching and isolation.
