带复位功能的8通道I²C总线开关

PCA9548A 正常供应

PCA9548A是一款8通道双向转换开关，通过I²C总线进行控制。SCL/SDA上游对会扇出8个下游对或通道。可选择任何单独的SCx/SDx通道或通道组合，由可编程控制寄存器的内容决定。

低电平有效的复位输入端允许PCA9548A从某个下游I²C总线停滞于低电平状态的情形中恢复过来。和内部上电复位功能一样，将RESET引脚拉至低电平也会将I²C总线状态机复位，并导致所有通道均处于未选定状态。

这些开关的传输门构造使得VDD引脚可用于限制PCA9548A传递的最大高压。这允许在各对上使用不同的总线电压，在没有任何额外保护的情况下使1.8V、2.5V或3.3V部件能够与5V部件进行通信。外部上拉电阻将总线上拉至每个通道所需的电压电平。所有I/O引脚均可容许6V电压。

The SCL/SDA upstream pair fans out to eight downstream pairs, or channels. Any individual SCx/SDx channel or combination of channels can be selected, determined by the contents of the programmable control register.

This bus is called the Inter-IC or I2C-bus. Only two bus lines are required: a serial data line (SDA) and a serial clock line (SCL). Serial, 8-bit oriented, bidirectional data transfers can be made at up to 100 kbit/s in the Standard-mode, up to 400 kbit/s in the Fast-mode, up to 1 Mbit/s in the Fast-mode Plus (Fm+), or up to 3.4 Mbit/s in the High-speed mode.
