74ls175工作原理
74ls175工作原理
上图中的74ALS175N为一四路的锁存器，当CLK引脚输入上涨沿时，1D-4D
被锁存到输出端（1Q-4Q）。
在CLK其他状态时，输出与输入无关。
电路通电后，按下复位按键S，1Q、Q2、Q三、Q4输出高电平。
电路进入筹办状态。
这时候，假设有按键A被按下，4D的输出将由低酿成高电平，使4Q 输输出为高电平经过或门U3A驱动数码管使数码管预示1（选手A的编号），同时使/4Q(4Q非)输出为低电平经过与门U4A输出低电平，此低电平与时钟脉冲经过与非门U2A形成一个上涨沿作为74LS175 CLK的输入。
因为74LS175是下降沿触发的，故按下除复位之外的不论什么的按键都将不会发生电路状态的变化，即输入被锁定。
达到了既定的功能方针。

sn74 74
74LS属于TTL类型的集成电路，而74HC属于CMOS集成电路。
LS、HC 二者高电平低电平定义不同，HC高电平规定为0.7倍电源电压，低电平规定为0.3倍电源电压。
LS规定高电平为2.0V，低电平为0.8V。
带负载特性不同。
HC上拉下拉能力相同，LS 上拉弱而下拉强。
输入特性不同。
HC输入电阻很高，输入开路时电平不定。
LS输入内部有上拉，输入开路时为高电平。
（1）74LS系列是“低功耗肖特基TTL”，统称74LS系列。
其改进型为“先进低功耗肖特基TTL”，既74ALS系列，它的性能比74LS更好。
（2）74HC系列，它具有CMOS的低功耗和相当于74LS高速度的性能，属于一种高速低功耗产品。
（3）上述两者的工作频率都在30mHz以下，74ALS略高，可达50mHz。
（4）但它们的工作电压却大不相同：74LS系列为5V，74HC系列为2~6V。
（5）扇出能力：74LS系列为20，而74HC系列在直流时则高达1000以上，但在交流时很低，由工作频率决定74HC属于CMOS系列，输入阻抗高，输出电压高（4.9V为逻辑1），驱动能力差；74LS属于TTL系列，输出电压较低（3.5V为逻辑1），驱动能力较强；与单片机匹配，关系不大，但尽量用同一类型的芯片，即74HC 系列74系列芯片功能大全7400 TTL 2输入端四与非门7401 TTL

INFORMATIONSN74CB3Q1624516-BIT SWITCH2.5-V/3.3-V LOW-VOLTAGE FET BUS SWITCHSCDS171A–JULY 2004–REVISED MARCH 2005The SN74CB3Q16245is a high-bandwidth FET bus switch utilizing a charge pump to elevate the gate voltage of the pass transistor,providing a low and flat ON-state resistance (r on ).The low and flat ON-state resistance allows for minimal propagation delay and supports rail-to-rail switching on the data input/output (I/O)ports.The device also features low data I/O capacitance to minimize capacitive loading and signal distortion on the data bus.Specifically designed to support high-bandwidth applications,the SN74CB3Q16245provides an optimized interface solution ideally suited for broadband communications,networking,and data-intensive computing systems.The SN74CB3Q16245is organized as two 8-bit bus switches with separate output-enable (1OE,2OE)inputs.It can be used as two 8-bit bus switches,or as one 16-bit bus switch.When OE is low,the associated 8-bit bus switch is ON,and the A port is connected to the B port,allowing bidirectional data flow between ports.When OE is high,the associated 8-bit bus switch is OFF,and a high-impedance state exists between the A and B ports.This device is fully specified for partial-power-down applications using I off .The I off circuitry prevents damaging current backflow through the device when it is powered down.The device has isolation during power off.To ensure the high-impedance state during power up or power down,OE should be tied to V CC through a pullup resistor;the minimum value of the resistor is determined by the current-sinking capability of the driver.ORDERING INFORMATIONT APACKAGE (1)ORDERABLE PART NUMBER TOP-SIDE MARKING Tube SN74CB3Q16245DL SSOP –DLCB3Q16245Tape and reel SN74CB3Q16245DLR –40°C to 85°CTube

74ls175集成寄存器引脚图及功用
74ls175集成寄存器引脚图及功用寄存器是核算机和别的数字系统顶用来存储代码或数据的逻辑部件。
它的首要构成有些是触发器。
一个触发器能存储1位二进制代码，所以要存储n位二进制代码的寄存器就需求用n个触发器构成。
一个4位的集成寄存器74LS175的逻辑电路图和引脚图别离如图1(a)、(b)所示。
其间,RD是异步清零操控端。
在往寄存器中寄存数据或代码之前，有必要先将寄存器清零,否则有或许犯错。
1D～4D 是数据输入端,在CP脉冲上升沿作用下，1D～4D端的数据被并行地存入寄存器。
输出数据能够并行从1Q～4Q端引出，也能够并行从1Q～4Q端引出反码输出。
图1集成寄存器74LS175(a)逻辑电路图(b)引脚图74LS175的功用如表1所示。

有时为了处理数据，需求将寄存器中的各位数据在移位操控信号作用下，顺次向高位或向低位移动1位。
具有移位功用的寄存器称为移位寄存器。

TRANSLATION AND 3-STATE OUTPUTSSCES515H–DECEMBER 2003–REVISED JANUARY 2007The SN74LVC1T45is designed for asynchronous communication between two data buses.The logic levels of the direction-control (DIR)input activate either the B-port outputs or the A-port outputs.The device transmits data from the A bus to the B bus when the B-port outputs are activated and from the B bus to the A bus when the A-port outputs are activated.The input circuitry on both A and B ports always is active and must have a logic HIGH or LOW level applied to prevent excess I CC and I CCZ .The SN74LVC1T45is designed so that the DIR input is powered by V CCA .This device is fully specified for partial-power-down applications using I off .The I off circuitry disables the outputs,preventing damaging current backflow through the device when it is powered down.The V CC isolation feature ensures that if either V CC input is at GND,then both ports are in the high-impedance state.NanoFree™package technology is a major breakthrough in IC packaging concepts,using the die as the package.FUNCTION TABLE (1)INPUT OPERATION DIR L B data to A bus HA data toB bus(1)Input circuits of the data I/Os always are active.LOGIC

ApplicationCalculate the enable times for the SN74LVC1T45using the following formulas:•t PZH (DIR to A)=t PLZ (DIR to B)+t PLH (B to A)•t PZL (DIR to A)=t PHZ (DIR to B)+t PHL (B to A)•t PZH (DIR to B)=t PLZ (DIR to A)+t PLH (A to B)•t PZL (DIR to B)=t PHZ (DIR to A)+t PHL (A to B)In a bidirectional application,these enable times provide the maximum delay from the time the DIR bit is switched until an output is expected.For example,if the SN74LVC1T45initially is transmitting from A to B,then the DIR bit is switched;the B port of the device must be disabled before presenting it with an input.After the B port has been disabled,an input signal applied to it appears on the corresponding A port after the specified propagation delay.PACKAGING INFORMATIONOrderable Device Status (1)Package

device recommended for new designs.LIFEBUY:TI has announced that the device will be discontinued,and a lifetime-buy period is in effect.NRND:Not recommended for new designs.Device is in production to support existing customers,but TI does not recommend using this part in a new design.PREVIEW:Device has been announced but is not in production.Samples may or may not be available.OBSOLETE:TIhas discontinued the production of the device.(2)Eco Plan -The planned eco-friendly classification:Pb-Free (RoHS),Pb-Free (RoHS Exempt),or Green (RoHS &no Sb/Br)-please check /productcontent for the latest availability information and additional product content details.TBD:The Pb-Free/Green conversion plan has not been defined.Pb-Free (RoHS):TI's terms "Lead-Free"or "Pb-Free"mean semiconductor products that are compatible with the current RoHS requirements for all 6substances,including the requirement that lead not exceed 0.1%by weight in homogeneous materials.Where designed to be soldered at high temperatures,TI Pb-Free products are suitable for use in specified lead-free processes.Pb-Free (RoHS Exempt):This component has a RoHS exemption for either 1)lead-based flip-chip solder bumps used between the die and package,or 2)lead-based die adhesive used between the die and leadframe.The component is otherwise considered Pb-Free (RoHS compatible)as defined above.Green (RoHS &no Sb/Br):TI defines "Green"to mean Pb-Free (RoHS compatible),and free of Bromine (Br)and Antimony (Sb)based flame retardants (Br or Sb do not exceed 0.1%by weight in homogeneous material)(3)MSL,Peak Temp.--The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications,and peak solder temperature.Important Information and Disclaimer:The information provided on this
