8-input multiplexer; 3-state
74HC251;74HCT251是8位复用器,带八个二进制输入(I0至I7)、三个选择输入(S0至S2)以及一个输出使能输入(OE)。选择输入选择八个二进制输入之一并将其路由到互补输出(Y和Y)。OE上的高电平使输出呈高阻抗关断状态。输入包括钳位二极管,其能使用限流电阻将输入连接到高于VCC的电压。

How does it work?
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.
