  • PCA9546A 4 channel I2C bus swi

    The PCA9546A is a quad bidirectional translating switch controlled via the I2C-bus. TheSCL/SDA upstream pair fans out to four downstream pairs, or channels. Any individualSCx/SDx channel or combination of channels can be selected, determined by thecontents of the programmable control register.

  • PCA9547D/PW/BS I2C多路复用器和开关

    PCA9547 是一款通过I2C 总线控制的八进制双向转换开关。它的每对SCL/ SDA 上行通道可以扩展为八对下行通道。但在某一时刻,由可编程控制寄存器中的内容来决定只有一路SCx/SDx 被选择。由多路复用器的通门,VDD 管脚可以用来限制PCA9547 通过的最高电压,这使得每一对SCL/SDA 可以使用不同的总线电压,因此1.8V、2.5V 或3.3V ...
