74ls32的工作原理
74ls32的工作原理"74LS32的工作原理"74LS32是一种集成电路,属于TTL(双极限制逻辑)系列。
它具有四个2输入或门(OR gate),它们的工作原理是将两个输入信号进行逻辑“或”运算,并产生一个相应的输出信号。
在本文中,我们将深入研究74LS32的工作原理,并逐步回答关于它的问题。
第一步:了解数码逻辑门在开始研究74LS32之前,我们首先需要了解数码逻辑门的基本概念。
逻辑门是一种用于对输入信号进行逻辑运算的电子元件。
最常见的数码逻辑门类型包括与门(AND gate)、或门(OR gate)、非门(NOT gate)、异或门(XOR gate)等。
第二步:介绍74LS32的外部引脚配置74LS32是一个四通道的或门,具有14个引脚。
这些引脚被用于电源连接、输入信号传输和输出信号接收等功能。
以下是74LS32的外部引脚配置:1. 引脚1和14:Vcc和GND,分别用于连接正负电源。
2. 引脚2和3:第一个或门的两个输入引脚。
3. 引脚4和5:第二个或门的两个输入引脚。
4. 引脚6和7:第三个或门的两个输入引脚。
5. 引脚8和9:第四个或门的两个输入引脚。
6. 引脚10:输出引脚1,对应第一个或门的输出。
7. 引脚11:输出引脚2,对应第二个或门的输出。
8. 引脚12:输出引脚3,对应第三个或门的输出。
9. 引脚13:输出引脚4,对应第四个或门的输出。
第三步:讨论74LS32的内部电路结构现在让我们来深入了解74LS32的内部电路结构,以回答关于它的工作原理的问题。
74LS32的内部电路由四个单独的或门组成,每个或门都具有两个输入和一个输出。
每个或门内部都有两个晶体管。
其中一种叫做“基极连接晶体管”,它的基极被连接到一个恒定的电压源,而另一种叫做“共射极晶体管”,它的发射极和基极都连接到两个输入引脚。
当输入A和输入B都为低电平(0V)时,恒定电压源会提供一个较高电压,并使基极连接晶体管工作,导致输出为高电平(5V)。

54/74374八上升沿D触发器(3S,时钟输入有回环特性)简要说明:374为具有三态输出的八D边沿触发器,共有54/74S374和54/74LS374两种线路结构型式,其主要电器特性的典型值如下(不同厂家具体值有差别):型号f m P D54S374/74S374 100MHz 450mW54LS374/74LS374 50MHz 135mW374的输出端O0~O7可直接与总线相连。
当三态允许控制端OE为低电平时,O0~O7为正常逻辑状态,可用来驱动负载或总线。
当OE为高电平时,O0~O7呈高阻态,即不驱动总线,也不为总线的负载,但锁存器内部的逻辑操作不受影响。
当时钟端CP脉冲上升沿的作用下,O随数据D而变。
由于CP端施密特触发器的输入滞后作用,使交流和直流噪声抗扰度被改善400mV。

© 2002 Fairchild Semiconductor Corporation DS500742May 2002Revised May 200274LVT322373 • 74LVTH322373 Low Voltage 32-Bit Transparent Latch with 3-STATE Outputs and 25Ω Series Resistors in the Outputs74LVT322373 • 74LVTH322373Low Voltage 32-Bit Transparent Latch with 3-STATE Outputsand 25Ω Series Resistors in the OutputsGeneral DescriptionThe LVT322373 and LVTH322373 contain thirty-two non-inverting latches with 3-STATE outputs and are intended for bus oriented applications. The device is byte controlled.The flip-flops appear transparent to the data when the Latch Enable (LE) is HIGH. When LE is LOW, the data that meets the setup time is latched. Data appears on the bus when the Output Enable (OE) is LOW. When OE is HIGH,the outputs are in a high impedance state.The LVTH322373 data inputs include bushold, eliminating the need for external pull-up resistors to hold unused inputs.These latches are designed for low voltage (3.3V) V CC applications, but with the capability to provide a TTL inter-face to a 5V environment. The LVT322373 and LVTH322373 are fabricated with an advanced BiCMOS technology to achieve high speed operation similar to 5V ABT while maintaining a low power dissipation.Featuress Input and output interface capability to systems at 5V V CC s Bushold data inputs eliminate the need for external pull-up resistors to hold unused inputs (74LVTH322373),also available without bushold feature (74LVT322373)s Live insertion/extraction permitteds Power Up/Down high impedance provides glitch-free bus loading s Outputs include equivalent series resistance of 25Ω to make external termination resistors unnecessary and reduce overshoot and undershoot s ESD performance:Human-body model > 2000V Machine model > 200V Charged-device model > 1000Vs Packaged in plastic Fine-Pitch Ball Grid Array (FBGA)Ordering Code:Note 1: Ordering Code “G” indicates Trays.Note 2: Devices also available in Tape and Reel.

The device is byte con-trolled with each byte functioning identically, but independent of the other. Control pins can be shorted together to obtain full 32-bit operation. The following description applies to each byte. When the Latch Enable (LE n ) input is HIGH, data on the D n enters the latches. In this condition the latches are transparent, i.e, a latch output will change states each time its D input changes. When LE n is LOW, the latches store information that was present on the D inputs a setup time preceding the HIGH-to-LOW transition of LE n . The 3-STATE standard outputs are controlled by the Output Enable (OE n ) input. When OE n is LOW, the standard outputs are in the 2-state mode. When OE n is HIGH, the standard outputs are in the high impedance mode but this does not interfere with entering new data into the latches.

当任意一个或多个输入引脚为高电平时,输出引脚会输出高电平。
5.74LS86-四个二输入异或门:该芯片包含了四个二输入异或门。
当任意一个输入引脚为高电平时,输出引脚输出高电平。
当所有输入引脚均为低电平或均为高电平时,输出引脚输出低电平。
6.74LS74-双D触发器:该芯片包含了两个D触发器。
D触发器是最常见的触发器类型之一,具有时钟信号、输入信号和输出信号三个引脚。
7.74LS138-三到八译码器:该芯片可以将三个二进制输入信号转换为八个输出信号,用于选择特定的输出。
8.74LS151-八输入数据选择器:该芯片可以选择八个输入信号中的一个进行输出。
9.74LS161-二进制计数器:该芯片可以实现二进制计数功能,根据时钟信号和控制信号的输入,将输出信号从0000(0)到1111(15)递增。
10.74LS245-八位双向总线收发器:该芯片可以实现八位数据的双向传输,可用于数据总线的驱动和接收。
这只是74系列芯片中的一小部分常用功能,还有很多其他功能的芯片,如时钟发生器、计时器、多路复用器等。
这些芯片广泛应用于数字电子系统的设计和实现中,可以帮助实现各种数字逻辑功能,提高电路的灵活性和可扩展性。
