●逻辑类型Logic Type| 非反相 Non-Inverting \---|--- 电路数Number of Circuits| 4 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)| 2.6mA，24mA 输出高，低电平电流Current - Output High, Low| These bus buffers feature three-state outputs . When disabled, both output transistors are turned off, presenting a high-impedance state to the bus so the output will act neither as a significant load nor as a driver. 低逻辑电平Logic Level - Low| 这些总线缓冲器具有三态输出。 禁用时，两个输出晶体管被关闭，呈现高阻抗状态，所以输出总线既不是一个显着的负载，也没有作为一个驱动器 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|
