The data bus must go into a high-impedancestate at least one cycle before output of the latest data.
在这种切换中，读出的数据有效前，数据总线至少需要有一个时钟的高阻状态。

The microcontroller's pin connects to ground using pulldown resistor R1 with resistance, typically, of a few hundred kilohms to impress the high-impedancestate on the pin.
微处理器管脚用下拉电阻R1与地相连，阻抗典型为几百千欧，在管脚上呈现出高阻状态。

When disabled, the output is switched to a highimpedancestate, making the HA4600 ideal for routing matrix equipment and video multiplexers.
