当有电话呼入时，电话线上传输的25HZ、90V 的交流振铃信号由C1、C2隔离直流后由整流桥整流，整流后的直流电压值较高，经光电隔离器U1后输出TTL脉冲信号，该脉冲经74LS123整形成大方波信号，该方波信号送至单片机的P3.5引脚进行计数，当计数值达到预设值时，单片机P1.0引脚输出高电平，三极管Q1导通则继电器K1动作，将负载电阻R5（330Ω）接入电路实现模拟摘机。

这里所说的模拟摘机是指将R5接入电路后，电话线上就会出现大于10mA的电流，交换中心检测到这一电流后就不再输出振铃信号而是转为接通电话。

人们手动摘机接通电话时的工作过程与此一致，因此称为模拟摘机。

如果振铃信号没有达到预设值就消失，则单片机的计数值清零，控制器不动作。

关于74ls244和74ls273两个芯片的介绍

关于74ls244和74ls273两个芯片的介绍74LS244为3态8位地址锁存器。

地址锁存器就是一个暂存器，它根据控制信号的状态，将总线上地址代码暂存起来。

8086/8088数据和地址总线采用分时复用操作方法，即用同一总线既传输数据又传输地址。

当微处理器与存储器交换信号时，首先由CPU发出存储器地址，同时发出允许锁存信号ALE给锁存器，当锁存器接到该信号后将地址/数据总线上的地址锁存在总线上，随后才能传输数据。

锁存器是一个很普通的时序电路。

一般的，它在时钟上升沿或者下降沿来的时候锁存输入，然后产生输出，在其他的时候输出都不跟随输入变化，这就是所谓边缘触发的D触发器。

当然也有电平触发的D触发器，具体使用哪种，得看你使用得总线配置。

通常用作单片机的地址锁存器的芯片有74LS373、8282、74LS273等。

74LS373和8282是带三态输出的8位锁存器，它们的结构和用法类似。

以74LS373为例，共有8个输入端D1—D8及8个输出端Q1—Q8。

当三态端OE为有效低电平，74LS373的G端为输人选通端，使能端G为有效高电平时，输出跟随输入变化；当G＝1时，锁存器处于透明工作状态，即锁存器的输出状态随数据端的变化而变化，即脚1=Di(I=1，2，…，8)。

当G端由1变0时，数据被锁存起来，此时输出端Qi不再随输入端的变化而变化，而一直保持锁存前的值不变。

G端(或STB端)可直接与单片机的锁存控制信号端ALE相连，在ALE的下降沿进行地址锁存。

只要根据“输入三态，输出锁存”的原则，选择74系列的TTL电路或MOS电路就能组成简单的扩展电路，如74LS244、74LS273、74LS373、74LS377等芯片都能组成输入、输出接口。

74ls42中文资料(BCD-十进制转换器)

74ls42中文资料目录74LS42简介 (1)使用条件 (1)详细介绍 (2)74LS42简介74LS42可以将输入的4位二进制数转换为十进制数输出。

由于输出的十进制数的范围为0-9，输入的二进制数的范围也是0-9，与4位BCD码的表示范围相同，因此也可以将74LS42称作BCD-十进制译码器，即将BCD码转换为十进制数。

使用条件在使用该芯片时，最好在如下的条件下使用：详细介绍该芯片的外观如图1所示，该芯片共16个引脚。

逻辑电路如图2所示。

其中12-15引脚为输入引脚，1-7,9-11为输出引脚。

图2未标注的16引脚为VCC，8引脚为GND。

该芯片的工作方式为，将12-15（即A-D）引脚输入的二进制数转换为十进制数，并在该十进制数对应的输出引脚编号上输出低电平，其余输出引脚输出高电平。

例如输入的二进制数为1001B，则11号引脚输出低电平，其余输出引脚输出低电平。

输入与输出具体关系见下表。

输入引脚输出引脚D C B A0123456789L L L L L H H H H H H H H HL L L H H L H H H H H H H HL L H L H H L H H H H H H HL L H H H H H L H H H H H H从上表可以看出，当输入的二进制数的范围在0-9时，该芯片的输出端总会有一个引脚是低电平。

但是当输入数据大于9之后，输出端不输入任何数据，即输出引脚都为高电平。

输出引脚的驱动能力为高电平10个单位TTL负载，低电平5个单位TTL负载。

（1个单位高电平TTL负载为40uA，低电平TTL负载为1.6mA）。
