The PCA9547 is an octal bidirectional translating multiplexer controlled by the I2C-bus.The SCL/SDA upstream pair fans out to eight downstream pairs, or channels. Only oneSCx/SDx channel can be selected at a time, determined by the

PCA9547 是一款通過(guò)I2C 總線控制的八進(jìn)制雙向轉(zhuǎn)換開關(guān)。它的每對(duì)SCL/ SDA 上行通道可以擴(kuò)展為八對(duì)下行通道。但在某一時(shí)刻，由可編程控制寄存器中的內(nèi)容來(lái)決定只有一路SCx/SDx

PCA9548 是NXP 公司生產(chǎn)的I2C 總線擴(kuò)展器件，通過(guò)它可以將1 路I2C 總線擴(kuò)展為8路。在對(duì)內(nèi)部控制寄存器進(jìn)行相應(yīng)配置后，可同時(shí)選擇1 路或多路下行I2C 總線與上行I2C總線連接。通過(guò)
