SN74HC258 具有三态输出的四路 2 线路到 1 线路数据选择器/多路复用器

These devices are designed to multiplex signals from 4-bit data sources to 4-output data lines in bus-organized systems. The 3-state outputs do not load the data lines when the output-enable (G\) input is at a high logic level.

To ensure the high-impedance state during power up or power down, (G\) should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver
