双JK触发器CD4027中文资料
CD4027功能：
CD4027是包含了2个相互独立的、互补对称的J－K主从触发器的单片集成电路。每个触发器分别提供了J、K置位、复位和时钟输入信号及经过缓冲的Q和Q输出信号，输入输出引出端排列与CC4013双D型触发器相似。CC4027可用于性能控制、寄存器和触发器等电路。加在J、K输入端的逻辑电平通过内部自行调整来控制每个触发器的状态，在时钟脉冲上升沿改变触发器状态，置位和复位功能与时钟无关，均为高电平有效。
从图可知，内部含有两套相同的JK触发器，（1）和（2）为输出端，（3）脚为前级时钟输入，（4）和（7）脚分别是复位和更新脚，本电路要将其接低电平，（5）和（6）脚为JK端，需接高电平。从（1）脚输出的信号既是所需要的1HZ方波。
