CD4017中文资料内容说明及其运用
CD4017中文资料内容说明及其运用电子制作2009-11-14 20:09:21 阅读5119 评论1 字号：大中小订阅cd4017中文资料内容说明cd4017中文资料内容说明：CD4017 是5 位Johnson 计数器，具有10 个译码输出端，CP、CR、INH 输入端。
时钟输入端的斯密特触发器具有脉冲整形功能，对输入时钟脉冲上升和下降时间无限制。
INH 为低电平时，计数器在时钟上升沿计数；反之，计数功能无效。
CR 为高电平时，计数器清零。
Johnson 计数器，提供了快速操作、2 输入译码选通和无毛刺译码输出。
防锁选通，保证了正确的计数顺序。
译码输出一般为低电平，只有在对应时钟周期内保持高电平。
在每10 个时钟输入周期CO 信号完成一次进位，并用作多级计数链的下级脉动时钟。
CD4017 提供了16 引线多层陶瓷双列直插(D)、熔封陶瓷双列直插(J)、塑料双列直插(P)和陶瓷片状载体(C)4 种封装形式。
引出端功能符号CO：进位脉冲输渊CP：时钟输入端CR：清除端INH：禁止端Q0-Q9 计数脉冲输出端VDD：正电源VSS：地CD4017组成的防抖动触摸开关电路这是一个实用点触发电路，可以方便的与各种电路组合使用，温度控制，光控，声控，射频遥控。
而只需把这些信号加到CD4017的CP端。
本电路使用一片十进制计数器CD4017，输出Y2和复位端RST相接，14脚每次到两个记数脉冲既复位。
其工作原理是220伏交流电经变压器降压、D1-D4整流、C1滤波后获得+9V直流电压。
C3、R2构成上电复位电路，CD4017复位后Y0输出高电平，Y1和Y2输出低电平，三极管V导通。
继电器吸合，其常开触点接通用电器。
K被按下后，C2迅速放电，14脚获得脉冲上升沿，触发CD4017记数，使Y0输出低电平，Y2仍保持低电平。
此时三极管V截止，继电器释放，用电器断电。
再次按下K时，C2再次放电，14脚又获得一个记数脉冲，CD4017的Y0和Y1输出低电平，Y2输出高电平，通过二极管D5将CD4017复位，Y0 输出高电平，Y1和Y2输出低电平，三极管V再次导通，继电器吸合。

4017芯片
数字电路CD4017的原理及应用电路2008/10/18 00:26数字电路CD4017是十进制计数／分频器，它的内部由计数器及译码器两部分组成，由译码输出实现对脉冲信号的分配，整个输出时序就是Q0、Q1、Q2、…、Q9依次出现与时钟同步的高电平，宽度等于时钟周期。
CD4017有10个输出端（Q0～Q9）和1个进位输出端～Q5-9。
每输入10个计数脉冲，～Q5-9就可得到1个进位正脉冲，该进位输出信号可作为下一级的时钟信号。
CD4017有3个输（MR、CP0和~CP1），MR为清零端，当在MR端上加高电平或正脉冲时其输出Q0为高电平，其余输出端（Q1～Q9）均为低电平。
CP0和～CPl是2个时钟输入端，若要用上升沿来计数，则信号由CP0端输入；若要用下降沿来计数，则信号由～CPl端输入。
设置2个时钟输入端，级联时比较方便，可驱动更多二极管发光。
由此可见，当CD4017有连续脉冲输入时，其对应的输出端依次变为高电平状态，故可直接用作顺序脉冲发生器。
CD4017有两个时钟端 CP 和 EN，若用时钟脉冲的上沿计数，则信号从 CP 端输入；若用下降沿计数，则信号从 EN 端输入。
设置两个时钟端是为了级联方便。
CD4017 与 CD4022 是一对姊妹产品，主要区别是 CD4022 是八进制的，所以译码输出仅有 Y0～Y7，每输入 8 个脉冲周期，就可得到一个进位输出，它们的管脚相同，不过 CD4022 的 6、9 脚是空脚。
cd4017方框图 cd4017引脚图一、用一个CD4017制成的彩灯电路1.用一个CD4017制作的彩灯电路如图1 所示。
cd4017电路图2.电路工作原理CD4017输出高电平的顺序分别是③、②、④、⑦、⑩、①、⑤、⑥、⑨脚，故③、②、④、⑦、⑩、①脚的高电平使6串彩灯向右顺序发光，⑤、⑥、③脚的高电平使6串彩灯由中心向两边散开发光。
各种发光方式可按自己的需要进行具体的组合，若要改变彩灯的闪光速度，可改变电容C1的大小。

cd4017工作原理详解（cd4017引脚图及功能
cd4017工作原理详解（cd4017引脚图及功能CD4017简介CD4017是一种十进制计数器/脉冲分配器。
CD4017是5位Johnson计数器，具有10个译码输出端，CP、CR、INH输入端。
时钟输入端的斯密特触发器具有脉冲整形功能，对输入时钟脉冲上升和下降时间无限制。
CD4017提供了16引线多层陶瓷双列直插（D）、熔封陶瓷双列直插（J）、塑料双列直插（P）和陶瓷片状载体（C）4种封装形式。
CD4017工作条件电源电压范围：3V-15V输入电压范围：0V-VDD工作温度范围M类：-55℃-125℃E类：-40℃-85℃CD4017引脚图及功能CO：进位脉冲输出CP：时钟输入端CR：清除端INH：禁止端Y0~Y9：计数脉冲输出端VDD：正电源VSS：地CD4017真值表cd4017工作原理cd4017计数器，提供了快速操作、2 输入译码选通和无毛刺译码输出。
防锁选通，保证了正确的计数顺序。
译码输出一般为低电平，只有在对应时钟周期内保持高电平。
在每10 个时钟输入周期CO 信号完成一次进位，并用作多级计数链的下级脉动时钟。
CD4017内部结构图图 2 CD4017 内部逻辑电原理图CD4017内部逻辑电原理图如图2所示。
它是由十进制计数器电路和时序译码电路两部分组成。
其中的D触发器Fl～F5构成了十进制约翰逊计数器，门电路5～14 构成了时序译码电路。
约翰逊计数器的结构比较简单．它实质上是一种串行移位寄存器。
除了第3个触发器是通过门电路15、16构成的组合逻辑电路作用于F3的D3端以外，其余各级均是将前一级触发器的输出端连接到后一级触发器的输入端D的，计数器最后—级的Q5端连接到第一级的D1端。
这种计数器具有编码可靠，工作速度快、译码简单，只需由二输入瑞的与门即可译码，且译码输出无过渡脉冲干扰等特点。
通常只有译码选中的那个输出端为高电平，其余输出端均为低电平。
约翰逊计数器状态如表1-1所示。

These counters are advanced on the positive edge of the clock signal when the clock enable sig-nal is in the logical “0” state.The configuration of the CD4017BC and CD4022BC per-mits medium speed operation and assures a hazard free counting sequence. The 10/8 decoded outputs are nor-mally in the logical “0” state and go to the logical “1” state only at their respective time slot. Each decoded output remains high for 1 full clock cycle. The carry-out signal completes a full cycle for every 10/8 clock input cycles and is used as a ripple carry signal to any succeeding stages.Featuress Wide supply voltage range: 3.0V to 15V s High noise immunity:0.45 V DD (typ.)s Low power Fan out of 2 driving 74LTTL compatibility:or 1 driving 74LS s Medium speed operation: 5.0 MHz (typ.)with 10V V DD s Low power:10 µW (typ.)s Fully static operationApplications•Automotive •Instrumentation •Medical electronics •Alarm systems •Industrial electronics •Remote meteringOrdering Code:Devices also available in T ape and Reel.

计数器种类很多，按构成计数器中的各触发器是否使用一个时钟脉冲源来分，有同步计数器和异步计数器。
根据计数制的不同，分为二进制计数器，十进制计数器和任意进制计数器。
根据计数的增减趋势，又分为加法、减法和可逆计数器。
还有可预置数和可编程序功能计数器等。
目前，无论是TTL还是CMOS集成电路，都有品种较齐全的中规模集成计数器。
2、中规模十进制计数器CD4017B有清除和置数等功能，其引脚排列及逻辑符号如CD4017：十进制计数器/脉冲分配器CD4017 是5 位Johnson 计数器，具有10 个译码输出端，CP、CR、INH 输入端。

CD4017有16支脚，除电源脚VDD及VSS为电源接脚，输入电压范围为3–15V之外，其余接脚为：A、频率输入脚：CLOCK(Pin14)，为频率信号的输入脚。
数字电路CD4017的原理及应用电路教案资料
数字电路CD4017的原理及应用电路数字电路CD4017的原理及应用电路数字电路CD4017是十进制计数／分频器，它的内部由计数器及译码器两部分组成，由译码输出实现对脉冲信号的分配，整个输出时序就是Q0、Q1、Q2、…、Q9依次出现与时钟同步的高电平，宽度等于时钟周期。
CD4017有10个输出端（Q0～Q9）和1个进位输出端～Q5-9。
每输入10个计数脉冲，～Q5-9就可得到1个进位正脉冲，该进位输出信号可作为下一级的时钟信号。
CD4017有3个输（MR、CP0和~CP1），MR为清零端，当在MR端上加高电平或正脉冲时其输出Q0为高电平，其余输出端（Q1～Q9）均为低电平。
CP0和～CPl是2个时钟输入端，若要用上升沿来计数，则信号由CP0端输入；若要用下降沿来计数，则信号由～CPl端输入。
设置2个时钟输入端，级联时比较方便，可驱动更多二极管发光。
由此可见，当CD4017有连续脉冲输入时，其对应的输出端依次变为高电平状态，故可直接用作顺序脉冲发生器。
CD4017有两个时钟端 CP 和 EN，若用时钟脉冲的上沿计数，则信号从 CP 端输入；若用下降沿计数，则信号从 EN 端输入。
设置两个时钟端是为了级联方便。
CD4017 与 CD4022 是一对姊妹产品，主要区别是 CD4022 是八进制的，所以译码输出仅有 Y0～Y7，每输入 8 个脉冲周期，就可得到一个进位输出，它们的管脚相同，不过 CD4022 的 6、9 脚是空脚。
cd4017方框图 cd4017引脚图一、用一个CD4017制成的彩灯电路1.用一个CD4017制作的彩灯电路如图 1 所示。
cd4017电路图2.电路工作原理CD4017输出高电平的顺序分别是③、②、④、⑦、⑩、①、⑤、⑥、⑨脚，故③、②、④、⑦、⑩、①脚的高电平使6串彩灯向右顺序发光，⑤、⑥、③脚的高电平使6串彩灯由中心向两边散开发光。
各种发光方式可按自己的需要进行具体的组合，若要改变彩灯的闪光速度，可改变电容C1的大小。

These counters are advanced on thepositive edge of the clock signal when the clock enable sig-nal is in the logical “0” state.The configuration of the CD4017BC and CD4022BC per-mits medium speed operation and assures a hazard freecounting sequence. The 10/8 decoded outputs are nor-mally in the logical “0” state and go to the logical “1” stateonly at their respective time slot. Each decoded outputremains high for 1 full clock cycle. The carry-out signalcompletes a full cycle for every 10/8 clock input cycles andis used as a ripple carry signal to any succeeding stages.Featuress Wide supply voltage range: 3.0V to 15Vs High noise immunity:0.45 V DD (typ.)s Low power Fan out of 2 driving 74LTTL compatibility:or 1 driving 74LSs Medium speed operation: 5.0 MHz (typ.)with 10V V DDs Low power:10 µW (typ.)s Fully static operationApplications•Automotive•Instrumentation•Medical electronics•Alarm systems•Industrial electronics•Remote meteringOrdering Code:Devices also available in Tape and Reel.

cd4017工作原理
cd4017工作原理CD4017工作原理。
CD4017是一款常用的集成电路，广泛应用于各种数字电子设备中。

那么，CD4017是如何实现这一功能的呢？接下来，我们将详细介绍CD4017的工作原理。
CD4017内部结构由触发器、移位寄存器和解码器组成。
在工作时，CD4017首先接收外部的时钟信号，然后根据时钟信号的脉冲来控制内部的触发器和移位寄存器进行工作。
当时钟信号输入时，CD4017会根据时钟信号的脉冲来改变输出端的状态，实现分频功能。
CD4017内部的触发器和移位寄存器是关键的部件，它们可以将输入的时钟信号进行分频，并且控制输出端的状态。
在CD4017内部，有10个输出端口，它们分别对应着不同的分频信号。
当时钟信号输入时，CD4017会根据时钟信号的脉冲来改变输出端口的状态，实现10位分频的功能。
此外，CD4017内部还包含解码器，解码器可以根据移位寄存器的状态来选择输出哪一个端口作为分频信号输出。
这样，CD4017可以实现10位分频的功能，输出10个相位相同但频率不同的信号。
总结一下，CD4017通过内部的触发器、移位寄存器和解码器，实现了对输入时钟信号的分频，输出10个相位相同但频率不同的信号。
这种工作原理使得CD4017在数字电子设备中有着广泛的应用，如LED灯控制、计数器、时序控制等领域。

音源输入电路和喇叭保护电路，其原理简介如下：
cd4017以及其外围电路组成音源切换电路，开关k是转换按钮，每按一下cd4017相应的某个脚将输出高电平，使与这个脚连接的三极管导通，连接在该三极管的继电器获电吸合，相应的音源触点接通，从而达到音源转换的功能，led为指示灯。
q1～q4和其外围元件组成直流检测电路，电阻r1～r4为取样电
路，电容c1～c4可虑掉音频交流成分，lin和rin分别接功放的左右输出端。
当功放输出端有直流成分输出并达到一定幅度时，q1～q4中相应的三极管导通，从而使三极管q5基极变成低电位，q5、q6截止，继电器j触点释放，切断扬声器与电路的连接，喇叭得到保护。
电容c5起延时的作用，电路接通电源后电容c5通过电阻r5对其充电，三极管q5基极为低电平不导通，随着充电过程的完成，q5基极电平变高导通，继电器吸合，扬声器延时接通，避免功放电路刚接通电源时产生的噪音从扬声器里发出。

CD4017引脚图,引脚功能及工作时序图
CD4017功能简述:
CD4017是5位Johnson计算器，具有10个译码输出端，CP，CR，INH输入端。
时钟输入端的斯密特触发器具有脉冲整形功能，对输入时钟脉冲上升和下降时间无限制。
INH为低电平时，计算器在时钟上升沿计数；反之，计数功能无效。
CR为高电平时，计数器清零。
Johnson计数器，提供了快速操作，2输入译码选通和无毛刺译码输出。
防锁选通，保证了正确的计数顺序。
译码输出一般为低电平，只有在对应时钟周期内保持高电平。
在每10个时钟输入周期CO信号完成一次进位，并用作多级计数链的下级脉动时钟。
CD4017引脚功能：

b、CARRY OUT（Pin12），进位脚，当4017计数10个脉冲之后，CARRY OUT将输出一个脉波，代表产生进位，共串级计数器使用。
D、控制脚：
a、CLEAR(Pin15)：清除脚或称复位(Reset)脚，当此脚为Hi时，会使CD4017的Q0为”1”，其余Q1-Q9为”0”。
b、CLOCK ENABLE(Pin13)，时序允许脚，当此脚为低电位，CLOCK输入脉波在正缘时，会使CD4017计数，并改变Q1-Q9的输出状态。
