74ls390工作原理(一)74LS390工作原理什么是74LS39074LS390是一种二进制分频器/计数器芯片，常用于数字逻辑系统中。

它由两个带有异步清零功能的Ripple type的BCD计数器串联而成。

74LS390的结构74LS390由两个独立的4位二进制计数器组成，每个计数器的输入和输出都可以独立地进行控制。

74LS390既可以作为计数器使用，也可以作为分频器使用。

74LS390的工作原理74LS390的计数是通过四个JK触发器和一个与门实现的。

JK触发器的时钟信号由输入的晶体时钟分频得到，分频系数由上面的控制引脚控制。

通过对计数器的控制，可以实现数值的增加或减少。

74LS390的应用74LS390常用于计数器、分频器、频率测量和脉冲生成等数字逻辑设计中。

在数字电子钟、电视机中也经常会用到它。

总结74LS390是一种十分常见的数字逻辑IC芯片，可以实现计数和分频等功能，应用广泛。

深入理解74LS390的工作原理对于数字逻辑系统的设计有着重要的意义。

74LS390的引脚功能以下是74LS390的引脚功能及其描述：引脚描述引脚描述CP1 第一个计数器的时钟输入CP0 第二个计数器的时钟输入MR 异步清零输入，清零后计数器输出为0QA-QD 第一个计数器的四个二进制输出QB-QG 第二个计数器的四个二进制输出CET 两个计数器的使能输入，使能为高电平有效TC 整个74LS390的借位输出，当计数器输出为0时为高电平Q/Q̅A̅-第一个计数器的四个输出和其反相输出Q/Q̅D̅Q/Q̅B̅-第二个计数器的四个输出和其反相输出Q/Q̅G̅74LS390的工作模式74LS390有两种工作模式：计数模式和分频模式。

在计数模式下，74LS390会对传入的时钟信号进行计数。

当计数器计数到最大值时，会通过TC引脚的高电平输出一个借位信号，并将计数器清零，重新开始计数。

在分频模式下，通过对CP1和CP0控制，可以设置计数器的分频系数，使得输出信号的频率等于输入信号的频率除以分频系数。

时钟电路是数字系统不可缺少的一个重要组成部分，因为数字电路只有在时钟电路的驱动下才可正常工作。

根据应用场合的不同，不同数字电路选择使用不同类型的时钟发生器。

因交通灯控制系统的秒信号精度不高，故可选用555定时器，也可选用RC环行振荡器，考虑到红灯亮的时间与倒计数的时间一致，本系统选用CD4060计数器来得到一个时钟脉冲。

本设计通过CD4060计数器产生的是2Hz的时钟脉冲，不符合系统要求的1Hz时针脉冲，所以需要一个分频电路，即把CD4060所产生的信号进行2分频。

该分频电路可以用任何一个二进制计数器来实现。

本文选用74HC390计数器来实现，74HC390是一个双二-五-十进制加法计数器，其引脚接法及功能如下所示：
①每个集成块中由2组计数器，每组计数器由两个计数器组成，共有4个计数器。

②每组计数器内有1个一位二进制计数器和1个五进制计数器。

它们可以单独计数，但清零时同时清零。

A，B为时钟脉冲的输入，下降沿触发。

QA，QB，QC，QD为计数输出。

③如1位二进制计数器的输出QA接上五进制计数器的时钟脉冲的输入B，则构成8421BCD码十进制的计数器。

A为时钟脉冲的输入，QA，QB，QC，QD为输出，QD是最高位；五进制计数器的输出QD接上二进制计数器时钟脉冲输入A，则构成5421BCD码十进制
的计数器，B为时钟脉冲的输入，QA，QB，QC，QD为输出，QA 是最高位。

④清零RD为异步清零，高电平有效。

在本电路中，将clka与CD4060脉冲发生器的时钟输出相连，Qa 即为1Hz时钟输出。

其具体电路如图3所示。
