74HC590: 8位二进制计数器,带输出寄存器;3态

74HC590是高速硅栅CMOS器件,与低功耗肖特基TTL (LSTTL)针脚兼容。该器件的规格符合JEDEC标准no. 7A。

74HC590是带一个存储寄存器和3态输出的8位二进制计数器。存储寄存器具有并行(Q0至Q7)输出。二进制计数器具有一个主复位计数器(MRC)和计数使能(CE)输入。计数器和存储寄存器具有单独的正沿触发时钟(CPC和CPR)输入。如果两个时钟连在一起,则计数器状态总是比寄存器超前一个计数。内部电路可防止因时钟使能所导致的计时。提供纹波进位输出(RCO)是为了实现级联。级联通过连接第一级的RCO与第二级的CE而实现。较大计数链的级联可通过将每一级的RCO与以下各级的计数器时钟(CPC)输入相连而实现。如果两个时钟连在一起,则计数器状态总是比寄存器超前一个计数。
