PCA9605是一款单片CMOS集成电路，适用于I²C总线、SMBus、DDC、PMBus及其他基于类似原理的系统应用中的总线缓冲。

缓冲器通过缓冲SCL和SDA线路以扩展总线负载极限，允许缓冲器两侧均为最大允许总线电容。

PCA9605附带用于时钟信号的单向缓冲器和用于数据信号的双向缓冲器。因此不支持采用时钟展宽的从器件。

在其最基本的使用中，缓冲器会允许已扩展数量的从器件连接至一个（或多个）主器件。在这种情况下，所有主器件均会定位在PCA9605的Sxx_IN侧。

方向引脚(DIR)会通过允许反转单向时钟信号以进一步增强此功能，从而允许缓冲器的两侧均为主器件。

使能(EN)功能允许隔离总线扇区。可以使系统的各个部分相继上线。这意味着可以轻松控制各种组件的启动、工作速度和负载。
