关于 触发器
触发器（Flip Flops）是用于在数字电路中存储单个位的电子组件。这些触发器充当基本的存储器件，并具有多个输入，包括一个或多个输入以传递要存储的数据，以及另一个输入以指示何时应该存储数据的时机。
有不同类型的触发器，如D（延迟），SR（设置-复位）和JK，每种触发器对其输入的信号都有独特的响应。这些触发器可以用于在数字电路中实现各种逻辑功能。
与锁存器不同，触发器是边沿敏感的设备。这意味着触发器内存储的逻辑状态仅在接收到有效的时钟信号并触发边沿转换的瞬间发生改变。这确保了数字电路内的精确时序和同步性，因为逻辑状态的变化正好在所需的时刻发生。
集成电路（IC）-逻辑-触发器被广泛应用于数字系统，如微处理器、存储单元和时序逻辑电路。它们在存储和操作数字信息方面起着至关重要的作用，使数字电子设备和系统能够正常运行和工作。
