PCA9306DCUR

The PCA9306 allows bidirectional voltage translations between 1.2 V and 5 V, without the use of a direction pin.

The low ON-state resistance (ron) of the switch allows connections to be made with minimal propagation delay.

When EN is high, the translator switch is ON, and the SCL1 and SDA1 I/O are connected to the SCL2 and SDA2 

I/O, respectively, allowing bidirectional data flow between ports. When EN is low, the translator switch is off, 

and a high-impedance state exists between ports.

PCA9306允许在1.2 V和5 V之间进行双向电压转换，无需使用方向引脚。开关的低导通电阻（ron）允许以小的传

播延迟进行连接。EN为高时，转换器开关打开，SCL1和SDA1 I/O分别连接到SCL2和SDA2 I/O，允许端口之间的

双向数据流。当EN低时，转换器开关关闭，端口之间存在高阻抗状态
