74AHC257;74AHCT257是高速硅栅CMOS器件,与低功耗肖特基TTL (LSTTL)针脚兼容。其规格符合JEDEC标准No. 7-A。
74AHC257;74AHCT257具有四个相同的2输入多路复用器,带3态输出,其从两个数据源选择4位数据并受控于公共数据选择输入。输入S为低电平时选中的是来自数据源0(1I0至4I0)的数据输入,输入S为高电平时选中的是来自数据源1(1I1至4I1)的数据输入。来自所选输入的数据以真正(非反相)形式出现在输出(1Y至4Y)处。74AHC257;74AHCT257是4极2位置开关的逻辑实施,其中开关位置由施加到输入S的逻辑电平确定。OE为高电平时,输出被强制为高阻抗关断状态。
输出的逻辑方程式为:
74AHC257;74AHCT257等同于74AHC258;74AHCT258,但具有非反相(真正)输出。

The interactive datasheets are based on the Nexperia MOSFET precision electrothermal models. With our interactive datasheets you can simply specify your own conditions interactively. Start by changing the values of the conditions. You can do this by using the sliders in the condition fields. By dragging the sliders you will see how the MOSFET will perform at the new conditions set.
