   What is a pca9546a?

   • The PCA9546A is a 4-channel, bidirectional translating switch for I2C buses that supports Standard-Mode (100 kHz) and Fast-Mode (400 kHz) operation. The PCA9546A features I2C control using a single 8-bit control register in which the four least significant bits control the enabling and disabling of the 4 switch channels of I2C data flow.

   What is a pca9546a pass-gate transistor?

   • The pass-gate transistors of the PCA9546A are constructed such that the VCC voltage can be used to limit the maximum voltage that is passed from one I2C bus to another.

   What voltage should a pca9546a supply voltage be set to?

   • Looking at Figure 7, we see that Vo(sw)(max) is at 2.7 V when the PCA9546A supply voltage is 3.5 V or lower, so the PCA9546A supply voltage could be set to 3.3 V. Pull-up resistors can then be used to bring the bus voltages to their appropriate levels (see Figure 14).

   How do I Reset my pca9546a?

   • In the event of a glitch or data corruption, PCA9546A can be reset to its default conditions by using the power-on reset feature. Power-on reset requires that the device go through a power cycle to be completely reset. This reset also happens when the device is powered on for the first time in an application.
