●逻辑类型Logic Type| 非反相 Non-Inverting \---|--- 电路数Number of Circuits| 1 输入数Number of Inputs| 1 电源电压VccVoltage - Supply| 4.5 V ~ 5.5 V 静态电流IqCurrent - Quiescent (Max)| 8mA，8mA 输出高，低电平电流Current - Output High, Low| single bus buffer gate/line driver with 3-state output. The output is disabled when the output-enable (OE) input is high. When OE is low, true data is passed from the A input to the Y output. 低逻辑电平Logic Level - Low| 单总线缓冲门/线路驱动器与3态输出。 当输出使能（OE）输入为高电平，输出被禁止。 OE为低时，真正的数据是通过从A输入到Y输出。 高逻辑电平Logic Level - High| 传播延迟时间@Vcc，CLMax Propagation Delay @ V, Max CL| Description & Applications| 描述与应用|
