Dual JK flip-flop with reset; negative-edge trigger
74HC73是符合JEDEC标准no. 7A的高速硅栅CMOS器件。它与低功耗肖特基TTL(LSTTL)引脚兼容。
774HC73是双路负沿触发JK型触发器,具有单独的JK时钟(nCP)和复位(nR)输入;以及补充nQ和nQ输出。
在时钟从高到低转换前的某个建立时间,J输入和K输入必须保持稳定,以进行可预测操作。
复位(nR)是异步有源低电平输入。低电平时,它会覆盖时钟和数据输入,将nQ输出强制为低电平和高电平。
时钟输入的施密特触发器动作使电路高度容许较缓慢的时钟上升时间和下降时间。

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.
