74HC166;74HCT166是8位串行或并行输入/串行输出移位寄存器。该类器件具有一个串行数据输入(DS)、八个并行数据输出(Q0至Q7)和一个串行输出(Q7)。并行使能输入(PE)为低电平时,来自D0至D7的数据在时钟输入(CP)下一次从低电平跃迁至高电平时会加载到移位寄存器中。PE为高电平时,数据随CP每次从低电平跃迁到高电平在DS处串行输入到寄存器。时钟使能输入(CE) 为低电平时,数据在CP从低电平跃迁到高电平时移位。CE上的高电平可禁用CP输入。输入包括能使用限流电阻将输入连接到高于VCC的电压的钳位二极管。

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.
