八D锁存器74HC573中文资料
74HC573特点:
·三态总线驱动输出
·置数全并行存取
·缓冲控制输入
·使能输入有改善抗扰度的滞后作用
原理说明:
M54HC563/74HC563/M54HC573/74HC573的八个锁存器都是透明的D型锁存器,当使能(G)为高时,Q 输出将随数据(D)输入而变。

当使能为低时,输出将锁存在已建立的数据电平上。

输出控制不影响锁存器的内部工作,即老数据可以保持,甚至当输出被关闭时,新的数据也可以置入。

这种电路可以驱动大电容或低阻抗负载,可以直接与系统总线接口并驱动总线,而不需要外接口。

特别适用于缓冲寄存器,I/O 通道,双向总线驱动器和工作寄存器。

74hc573可以驱动几位共阴数码管?74hc573驱动数码管应用解析

74hc573可以驱动几位共阴数码管?74hc573驱动数码管应用解析

74hc573可以驱动几位共阴数码管?74hc573驱动数码管应用解析74hc573能够驱动几位共阴数码管取决于你使用几片74hc573,如果用两片,一片锁存段码,一片锁存位码,就可以驱动8位数码管。

在讲解74hc573驱动数码管问题之前我们要清楚,什么是74hc573及什么是数码管?数码管数码管是一种半导体发光器件,其基本单元是发光二极管,文章用到的是2位连体共阴数码管。

这种数码管有8根段码引脚和2根位码引脚,段码决定了显示的是什么字符,位码决定了哪位数码管被点亮。

对于共阴数码管来讲,位码引脚为低电平时,相应的数码管被点亮。

74hc573锁存器74HC573是拥有八路输出的透明锁存器,输出为三态门,是一种高性能硅栅CMOS器件。

具有8个数据输入端、8个数据输出端和3个控制端。

1脚(OE)为输出使能端,11脚(LE)为锁存使能端。

锁存器的工作原理:当OE为高时,输出为高阻态,即锁存器不能正常工作。

当OE为低且LE为高时,输出Q将随输入D而变,此时锁存器工作在直通模式下。

当OE为低且LE为低时,输出Q将不随输入D而变,此时锁存器工作在锁存模式下,输出Q保持上一时刻数值不变。

74hc573可以驱动几位共阴数码管?理论上说只要你74hc573使用得够多,就能驱动更多的数码管,下面来分享74hc573驱动数码管的应用电路及程序分享74hc573驱动2位数码管在程序开头部分先定义1个数组,数组元素为数码管的段码:uchar+code+table[]={0x3f,0x06,0x5b,0x4f,0x66%,0x6d,0x7d,0x07,0x7f,0x6f}关键代码及注释如下。

数据拆分和显示函数该函数在具体实现时,不停地先送显个位数,然后送显十位数,即采用了数码管动态扫描法。

扫描间隔不宜太长,文章为1毫秒,用delay(1)实现这个间隔,若扫描间隔太长,会导致扫描刷新不及时,出现个位和十位交替闪烁的现象。

定时计数器的初始化及其中断函数结论本电路采用单片机作为主控制器,设计了0-99循环计数并显示的电路,采用了锁存器实现2位数码管动态扫描显示。

74hc573的原理介绍74HC573和74LS373原理一样,8数据锁存器。

主要用于数码管、按键等等的控制1. 真值表Dn LE OE OnH H L HL H L LX L L QoX X H Z这个就是真值表,表示这个芯片在输入和其它的情况下的输出情况。

每个芯片的数据手册(datasheet)中都有真值表。

布尔逻辑比较简单,在此不赘述;2. 高阻态就是输出既不是高电平,也不是低电平,而是高阻抗的状态;在这种状态下,可以多个芯片并联输出;但是,这些芯片中只能有一个处于非高阻态状态,否则会将芯片烧毁; 高阻态的概念在RS232和RS422通讯中还可以用到。

3. 数据锁存当输入的数据消失时,在芯片的输出端,数据仍然保持;这个概念在并行数据扩展中经常使用到。

4. 数据缓冲加强驱动能力。

74LS244/74LS245/74LS373/74LS573都具备数据缓冲的能力。

OE:output_enable,输出使能;LE:latch_enable,数据锁存使能,latch是锁存的意思;Dn:第n路输入数据;On:第n路输出数据;再看这个真值表,意思如下:第四行:当OE=1是,无论Dn、LE为何,输出端为高阻态;第三行:当OE=0、LE=0时,输出端保持不变;第二行第一行:当OE=0、LE=1时,输出端数据等于输入端数据;结合下面的波形图,在实际应用的时候是这样做的:a.OE=0;b.先将数据从单片机的口线上输出到Dn;c.再将LE从0->1->0d.这时,你所需要输出的数据就锁存在On上了,输入的数据在变化也影响不到输出的数据了;实际上,单片机现在在忙着干别的事情,串行通信、扫描键盘……单片机的资源有限啊。

在单片机按照RAM方式进行并行数据的扩展时,使用movx @dptr, A这条指令时,这些时序是由单片机来实现的。

后面的表格中还有需要时间的参数,你不需要去管它,因为这些参数都是几十ns级别的,对于单片机在12M下的每个指令周期最小是1us的情况下,完全可以实现;如果是你自己来实现这个逻辑,类似的指令如下:mov P0,A ;将数据输出到并行数据端口clr LEsetb LEclr LE ;上面三条指令完成LE的波形从0->1->0的变化74ls573跟74LS373逻辑上完全一样,只不过是管脚定义不一样,数据输入和输出端。

74hc573锁存器作用
在LED和数码管显示方面,要维持一个数据的显示,往往要持续的快速的刷新。

尤其是在四段八位数码管等这些要选通的显示设备上。

在人类能够接受的刷新频率之内,大概每三十毫秒就要刷新一次。

这就大大占用了处理器的处理时间,消耗了处理器的处理能力,还浪费了处理器的功耗。

锁存器的使用可以大大的缓解处理器在这方面的压力。

当处理器把数据传输到锁存器并将其锁存后,锁存器的输出引脚便会一直保持数据状态直到下一次锁存新的数据为止。

这样在数码管的显示内容不变之前,处理器的处理时间和IO 引脚便可以释放。

可以看出,处理器处理的时间仅限于显示内容发生变化的时候,这在整个显示时间上只是非常少的一个部分。

而处理器在处理完后可以有更多的时间来执行其他的任务。

这就是锁存器在LED和数码管显示方面的作用:节省了宝贵的MCU时间。

锁存器和缓冲器的作用和区别
锁存器就是把当前的状态锁存起来,使CPU送出的数据在接口电路的输出端保持一段时间锁存后状态不再发生变化,直到解除锁定。

还有些芯片具有锁存器,比如芯片74LS244就具有锁存的功能,它可以通过把一个引脚置高后,输出就会保持现有的状态,直到把该引脚清0后才能继续变化。

缓冲寄存器又称缓冲器,它分输入缓冲器和输出缓冲器两种。

前者的作用是将外设送来的数据暂时存放,以便处理器将它取走;后者的作用是用来暂时存放处理器送往外设的数据。

有了数控缓冲器,就可以使高速工作的CPU与慢速工作的外设起协调和缓冲作用,实现数据传送的同步。

由于缓冲器接在数据总线上,故必须具有三态输出功能。

74hc573中文资料参数-74hc573引脚图-功能原理-74hC573的作用-应用电路-74hC563-54hC57高性能硅门CMOS器件SL74HC573跟LS/AL573的管脚一样。

器件的输入是和标准CMOS输出兼容的;加上拉电阻,他们能和LS/ALSTTL输出兼容。

当锁存使能端为高时,这些器件的锁存对于数据是透明的(也就是说输出同步)。

当锁存使能变低时,符合建立时间和保持时间的数据会被锁存。

×输出能直接接到CMOS,NMOS和TTL接口上×操作电压范围:2.0V~6.0V×低输入电流:1.0uA×CMOS器件的高噪声抵抗特性·三态总线驱动输出·置数全并行存取·缓冲控制输入·使能输入有改善抗扰度的滞后作用原理说明:M54HC563/74HC563/M54HC573/74HC573的八个锁存器都是透明的D 型锁存器,当使能(G)为高时,Q 输出将随数据(D)输入而变。

当使能为低时,输出将锁存在已建立的数据电平上。

输出控制不影响锁存器的内部工作,即老数据可以保持,甚至当输出被关闭时,新的数据也可以置入。

这种电路可以驱动大电容或低阻抗负载,可以直接与系统总线接口并驱动总线,而不需要外接口。

特别适用于缓冲寄存器,I/O 通道,双向总线驱动器和工作寄存器。
