低逻辑电平
Logic Level - Low | The SN74CBT3125 quadruple FET bus switch features independent line switches. Each switch is disabled when the associated output-enable (OE) input is high.To ensure the high-impedance state during power up or power down, OE 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.

高逻辑电平
Logic Level - High | SN74CBT3125四场效应管总线开关设有独立的线路开关。每个开关被禁用时，相关的输出使能（OE）输入为高。为了确保在开机或断电高阻抗状态，OE应当通过上拉电阻连接到VCC;驱动器的电流吸收能力确定电阻的最小值。 标准'125-型接脚分布（D，DB，DGV，PW包） 5Ω开关连接两个端口之间 TTL兼容的输入电平 |
