CD4013:双D触发器中文资料
CD4013由两个相同的、相互独立的数据型触发器构成。每个触发器有独立的数据、置位、复位、时钟输入和Q及Q输出,此器件可用作移位寄存器,且通过将Q输出连接到数据输入,可用作计算器和触发器。在时钟上升沿触发时,加在D输入端的逻辑电平传送到Q输出端。置位和复位与时钟无关,而分别由置位或复位线上的高电平完成。838电子

图4 切换时间波形 应用电路:置位和复位电路 图5(左)和图(右)中的CD4013是CMOS双D触发器,这类电路置位和复位信号是高电平有效,由于开关闭合时电容可视为短路而产生高电平,使RD=1,Q=0;若将此信号加到SD,则SD=1,Q=1;置位、复位过后,电容充电而使RD(SD)变为0,电路可进入计数状态。
