摘要： When a selection signal of a low signal is applied to a first port, a second port becomes either a low or a high signal in accordance with an input signal being a low or a high signal at a third port and the third port can be used as an input port. Further, when a completely synchronized low or high signal is inputted to the first port and the second port, a signal of either a low or a high signal inputted to the second port can be outputted from the third port as it is and the third port can be used as an output port.

摘要翻译： 当低信号的选择信号被施加到第一端口时，第二端口根据在第三端口处的低信号或高信号的输入信号变为低信号或高信号，并且可以使用第三端口 作为输入端口。 此外，当完全同步的低或高信号被输入到第一端口和第二端口时，可以从第三端口原样输出输入到第二端口的低信号或高信号的信号，并且第三端口 可用作输出端口。
