雙JK觸發器CD4027中文資料
CD4027功能：
CD4027是包含了2個相互獨立的、互補對稱的J－K主從觸發器的單片集成電路。每個觸發器分別提供了J、K置位、復位和時鐘輸入信號及經過緩沖的Q和Q輸出信號，輸入輸出引出端排列與CC4013雙D型觸發器相似。CC4027可用于性能控制、寄存器和觸發器等電路。加在J、K輸入端的邏輯電平通過內部自行調整來控制每個觸發器的狀態，在時鐘脈沖上升沿改變觸發器狀態，置位和復位功能與時鐘無關，均為高電平有效。
從圖可知，內部含有兩套相同的JK觸發器，（1）和（2）為輸出端，（3）腳為前級時鐘輸入，（4）和（7）腳分別是復位和更新腳，本電路要將其接低電平，（5）和（6）腳為JK端，需接高電平。從（1）腳輸出的信號既是所需要的1HZ方波。
