74HC75Quad bistable transparant latchRev. 03 — 12 November 2004Product data sheet1.General descriptionThe 74HC75 is a high-speed Si-gate CMOS device and is pin compatible with low powerSchottky TTL (LSTTL). The 74HC75 is speciﬁed in compliance with JEDECstandard no.7A.The 74HC75 has four bistable latches. The two latches are simultaneously controlled byone of two active HIGH enable inputs (LE12 and LE34). When LEnn is HIGH, the dataenters the latches and appears at the nQ outputs. The nQ outputs follow the data inputs(nD) as long as LEnn is HIGH (transparent). The data on the nD inputs one set-up timeprior to the HIGH-to-LOW transition of the LEnn will be stored in the latches. The latchedoutputs remain stable as long as the LEnn is LOW.2.Featuress Complementary Q and Q outputss V CC and GND on the center pinss Low-power dissipations Complies with JEDEC standard no.7As ESD protection:x HBM EIA/JESD22-A114-B exceeds 2000Vx MM EIA/JESD22-A115-A exceeds 200V.s Multiple package optionss Speciﬁed from−40°C to+80°C and from−40°C to+125°C.3.Quick reference data[1]C PD is used to determine the dynamic power dissipation (P D in µW).P D =C PD ×V CC 2×f i ×N +∑(C L ×V CC 2×f o )where:f i =input frequency in MHz;f o =output frequency in MHz;C L =output load capacitance in pF;V CC =supply voltage in V;N =number of inputs switching;∑(C L ×V CC 2×f o )= sum of outputs.4.Ordering informationTable 1:Quick reference data Symbol Parameter Conditions Min Typ Max Unitt PHL , t PLHpropagation delay C L =15pF;V CC =5VnD to nQ, nQ -11-ns LEnn to nQ, nQ-11-ns C I input capacitance - 3.5-pF C PDpower dissipation capacitance per latchV I =GND to V CC[1]-42-pFTable 2:Ordering informationType numberPackageTemperature rangeName DescriptionVersion 74HC75N −40°C to +125°C DIP16plastic dual in-line package; 16leads (300mil)SOT38-474HC75D −40°C to +125°C SO16plastic small outline package; 16leads;body width 3.9mmSOT109-174HC75DB −40°C to +125°C SSOP16plastic shrink small outline package; 16leads;body width 5.3mmSOT338-174HC75PW−40°C to +125°CTSSOP16plastic thin shrink small outline package;16leads; body width 4.4mmSOT403-15.Functional diagramFig 1.Functional diagram Fig 2.Logic symbol001aab853L1D CP16213Q1L2D CP153Q14L3D CP10641D LE122D3D LE34Q11L4D CP974DQ81Q 1Q2Q 2Q3Q 3Q4Q 4Q001aab8511D LE12L1,2L3,4LE341341Q 1Q 2Q 2Q 3Q 3Q 4Q 4Q2D3D 4D891110141511627636.Pinning information6.1PinningFig 3.IEC logic symbol Fig 4.Logic diagram001aab8524C171D986101113C121D16131514001aab854LATCH 1D CP 1Q 1D LE12Q 1QLATCH 2D CP 2Q 2D Q 2QLATCH 3D CP 3Q 3D LE34Q 3QLATCH 4D CP 4Q 4D Q 4QFig 5.Pin conﬁguration751Q 1Q 1D 2Q 2D 2Q LE34LE12V CC GND 3D 3Q 4D 3Q 4Q4Q001aab850123456781091211141316156.2Pin descriptionTable 3:Pin descriptionSymbol Pin Description1Q1complementary latch output 11D2data input 12D3data input 2LE344latch enable input for latches 3 and 4 (active HIGH)V CC5positive supply voltage3D6data input 34D7data input 44Q8complementary latch output 44Q9latch output 43Q10latch output 33Q11complementary latch output 3GND12ground (0V)LE1213latch enable input for latches 1 and 2 (active HIGH)2Q14complementary latch output 22Q15latch output 21Q16latch output 17.Functional description7.1Function tableTable 4:Function table[1]Operating mode Input OutputLEnn nD nQ nQData enabled H L L HH H H LData latched L X q q[1]H=HIGH voltage level;L=LOW voltage level;q=lower case letters indicate the state of the referenced output one set-up time prior to the HIGH-to-LOWLEnn transition;X=don’t care.8.Limiting values[1]Above 70°C: P tot derates linearly with 12mW/K.[2]Above 70°C: P tot derates linearly with 8mW/K.9.Recommended operating conditionsTable 5:Limiting valuesIn accordance with the Absolute Maximum Rating System (IEC 60134).

HD74BC574AOctal D Type Flip Flops With 3 State OutputsADE-205-042A (Z)2nd. EditionSep. 2000 DescriptionThe HD74BC574A provides high drivability and operation equal to or better than high speed bipolar standard logic IC by using Bi-CMOS process. The device features low power dissipation that is about 1/5 of high speed bipolar logic IC, when the frequency is 10 MHz. The device has eight edge triger D type flip flops with three state outputs in a 20 pin package. Data at the D inputs meeting set up requirements, are transferred to the Q outputs on positive going transitions of the clock input. When the latch enable goes low, data at the D inputs will be retained at the outputs until latch enable returns high again. When a high logic level is applied to the output control input, all outputs go to a high impedance state, regardless of what signals are present at the other inputs and the state of the strage elements.Features• Input/Output are at high impedance state when power supply is off.• Built in input pull up circuit can make input pins be open, when not used.• TTL level input• Wide operating temperature rangeTa = –40 to + 85°CHD74BC574A2Function TableInputsOutput Control CKD Output QL H HL L L L L X Q 0H X XZH :High level L :Low level X :ImmaterialZ:High impedance: Low to high transition Q 0:Level of Q before the indicated steady state input conditions were established.Pin ArrangementHD74BC574A3Absolute Maximum RatingsItemSymbol Rating Unit Supply voltage V CC –0.5 to +7.0V Input diode current I IK ±30mA Input voltage V IN –0.5 to +7.5V Output voltage V OUT –0.5 to +7.5V Off state output voltage V OUT(off)–0.5 to +5.5V Storage temperature Tstg–65 to +150°CNote:1.The absolute maximum ratings are values which must not individually be exceeded, andfurthermore, no two of which may be realized at the same time.Recommended Operating ConditionsItemSymbol Min Typ Max Unit Supply voltage V CC 4.5 5.0 5.5V Input voltage V IN 0—V CC V Output voltage V OUT 0—V CC V Operating temperature Topr –40—85°C Input rise/fall time*1t r , t f—8ns/VNote:1.This item guarantees maximum limit when one input switches.Waveform: Refer to test circuit of switching characteristics.HD74BC574A Logic Diagram4HD74BC574A5Electrical Characteristics (Ta = –40°C to +85°C)Item Symbol V CC (V)Min Max Unit Test ConditionsInput voltage V IH 2.0—V V IL —0.8V Output voltageV OH 4.5 2.4—V I OH = –3 mA 4.5 2.0—V I OH = –15 mA V OL4.5—0.4V I OL = 24 mA 4.5—0.5V I OL = 48 mA Input diode voltage V IK 4.5—–1.2V I IN = –18 mA Input currentI I5.5—–250µA V IN = 0 V 5.5— 1.0µA V IN = 5.5 V 5.5—100µA V IN = 7.0 V Short circuit output current*1I OS 5.5–100–225mA V IN = 0 or 5.5 V Off state output current I OZH 5.5—50µA V O = 2.7 V I OZL 5.5—–50µA V O = 0.5 V Supply currentI CCL 5.5—29.5mA V IN = 0 or 5.5 V All outputs is “L”I CCH 5.5— 2.5mA V IN = 0 or 5.5 V All outputs is “H”I CCZ 5.5— 2.5mA V IN = 0 or 5.5 V All outputs is “Z”I CCT *25.5—1.5mAV IN = 3.4 or 0.5 V Notes: 1.Not more than one output should be shorted at a time and duration of the short circuit should notexceed one second.2.When input by the TTL level, it shows I CC increase at per one input pin.HD74BC574A6Switching Test Method (C L = 50 pF)Ta = 25°C V CC = 5.0 VTa = –40 to 85°C V CC = 5.0 V ±10%Item SymbolMin Max Min Max Unit Test conditions Propagation CK →Q t PLH3.08.0 3.010.0nsSee under figuredelay time t PHL 3.08.0 3.010.0Output enable time t ZH 3.09.0 3.011.0ns t ZL 3.09.0 3.011.0Output disable time t HZ 3.08.0 3.010.0ns t LZ 3.08.0 3.010.0Setup time t s (H) 2.0— 2.0—ns t s (L) 2.0— 2.0—Hold time t h (H) 2.0— 2.0—ns t h (L) 2.0— 2.0—Pulse width t W (H) 6.0— 6.0—ns t W (L) 6.0—6.0—Input capacitance C IN 3.0 (Typ)——pF V IN = V CC or GND Output capacitanceC O15.0 (Typ)—pFV O = V CC or GNDTest CircuitHD74BC574A Waveforms-1Waveforms-27HD74BC574A8Waveforms-3Notes:1.t r = 2.5 ns, t f = 2.5 ns2.Input waveform: PRR = 1 MHz, duty cycle 50%3.Waveform-A shows input conditions such that the output is “L” level when enable by the output control.4.Waveform-B shows input conditions such that the output is “H” level when enable by the output control.HD74BC574A Package Dimensions9HD74BC574A10HD74BC574A11Cautions 1.Hitachi neither warrants nor grants licenses of any rights of Hitachi’s or any third party’s patent,copyright, trademark, or other intellectual property rights for information contained in this document.Hitachi bears no responsibility for problems that may arise with third party’s rights, includingintellectual property rights, in connection with use of the information contained in this document.2.Products and product specifications may be subject to change without notice.

The 8 flip-flops will store the state of their individual D-inputs that meet the set-up and hold time requirements on the LOW-to-HIGH CP transition. When OE is LOW, the contents of the 8 flip-flops are available at the outputs. When OE is HIGH, the outputs go to the high impedance OFF-state. Operation of the OE input does not affect the state of the flip-flops.

74ls574芯片中文使用手册说明书

特点：逻辑图说明：LS574的八个触发器是边沿触发D 型触发器。

在时钟的正跳动，Q 输出将处于D 输入端已建立的逻辑状态。

时钟线上的施密特触发缓冲输入将简化系统设计，因为输入滞后作用使交流和直流抗扰度一般提高400mV 。

缓冲输出的控制输入将使八个输出处于正常状态（高电平或低电平）或处于高阻状态。

在高阻态下，输出既不能有效地给总线加负载，也不能有效地驱动总线。

输出控制不影响触发器的内部工作，既老数据可以保持，甚至当输出被关闭，新的数据也可以置入。

74LS系列与74HC

74LS系列与74HC，74HCT，CD系列的区别一、概述：74LS是TTL电路的一个系列，TTL电路以双极型晶体管为开关元件所以以称双极型（电子和空穴）集成电路。

74HC是CMOS电路，CMOS电路是MOS电路中的主导产品。

MOS电路以绝缘栅场效应晶体管为开关元件。

所以又称单极型集成电路。

按其导电沟道的类型，MOS电路可分为PMOST 、NMOS和CMOS电路。

CMOS电路沿着4000A--4000B/4500B（统一称为4000B）--74HC/74vHC--74HCT系列高速发展。

HCT系列还同TTL电平兼容，扩大了应用范围。

CD代表标准的4000系列CMOS电路，我国生产的CMOS电路系列为“CC4000B”。

二、TTL逻辑芯片与与CMOS逻辑芯片的区别1.TTL工作电压范围为5V正负左右。

CMOS为3--18V左右。

2.频率特性：标准TTL电路在5MHZ以下，一般COMS在100KHZ以下。

3.速度*功耗积：（在100KHZ时，单位为PJ）标准TTL电路和为100。

标准CMOS为11。

4.最小输出的驱动电流（单位MA，输出低电平0.4V）标准输出：标准TTL系列为16。

标准COMS（4000系列为16，74系列为4）。

5.大电流输出：标准TTL为48V。

标准COMS（4000为16，74系列为6）6.扇出能力：标准TTL为系列为40（大电流输出为120）。

标准COMS（4000系列为4，74系列为10，大电流输出为4，15）。

7.最大输入电流（单位MA，输出低电平4V）：标准TTL系列为-1.6。

Note 1: Absolute maximum ratings are those values beyond which damage to the device may occur. The databook specifications should be met, without exception, to ensure that the system design is reliable over its power supply, temperature, and output/input loading variables. Fairchild does not recommend operation of FACT¥ circuits outside databook specifications.
The AC/ACT574 consists of eight edge-triggered flip-flops with individual D-type inputs and 3-STATE true outputs. The buffered clock and buffered Output Enable are common to all flip-flops. The eight flip-flops will store the state of their individual D-type inputs that meet the setup and hold time requirements on the LOW-to-HIGH Clock (CP) transition. With the Output Enable (OE) LOW, the contents of the eight flip-flops are available at the outputs. When OE is HIGH, the outputs go to the high impedance state. Operation of the OE input does not affect the state of the flipflops.

74H574使用心得

74HC574应用电路原理图寄存器是一种重要的数字电路部件, 常用来暂时存放数据、指令等。

一个触发器可以存储一位二进制代码，存放N位二进制代码，用N个触发器即可。

因为我们的模型机是8位的，因此在本模型机中大部分寄存器是8位的，标志位寄存器(Cy, Z)是二位的。

在COP2000实验仪中，寄存器由74HC574构成，它可以存放8位二进制代码，其中的一位二进制代码是由一个D触发器来存储的。

首先，我们先介绍一下74HC574的工作原理。

图2-1是74HC574的原理图。

图2-1 74HC574原理图我们可以看到，在CLK的上升沿，输入端的数据被打入到8个触发器中。

当OC = 1 时，触发器的输出被关闭，当OC=0时，触发器输出数据。

表2-1列出了74HC574的使用方法。

表2-1 74HC574使用方法从这个原理图中我们看不怎么明白在我编程的时候该怎么写代码如何使用我在这里使用了proteus软件仿真，使用KEIL软件编写代码：电路图：代码：#include <REG52.H>#define uchar unsigned char main(){P3=0X01;P2=0X01;//P3=0X00;//P2=0X00;}图2代码：#include <REG52.H>#define uchar unsigned charmain(){P3=0X01;P2=0X01;P3=0X00;//P2=0X00;}图3代码#include <REG52.H>#define uchar unsigned charmain(){P2=0X01;P3=0X01;P3=0X00;P2=0X00;}总结如果要使用74H574芯片做寄存器先要给端口赋值然后让CLK端口从低到高电频，把数据输入到寄存器，然后把CLK从搞到低锁存数据。

这个过程就是数据锁存了。
