74HC(T)4520: 双通道4位同步二进制计数器
74HC4520；74HCT4520是双通道4位内部同步二进制计数器，具有两个时钟输入（nCP0和nCP1）。它们具有来自所有4位位置（nQ0至nQ3）的缓冲输出和异步主机复位输入(nMR)。当nCP1为高电平时，此计数器在nCP0从低至高转变时递增。当nCP0为低电平时，它也会在nCP1从低至高转变时递增。nCP0或nCP1均可用作计数器的时钟输入。其他时钟输入可用作时钟使能输入。nMR为高电平时将会复位此计数器（nQ0至nQ3 = 低电平），不受nCP0和nCP1的影响。输入端包括钳位二极管。支持使用限流电阻将输入连接至超过VCC的电压。
