74hc系列芯片
74hc系列芯片74HC系列芯片是由NXP公司生产的一种CMOS逻辑集成电路系列。
此系列芯片的特点是功耗低、工作速度快、输入输出电平兼容TTL、输入阻抗高、噪声抑制性能好、工作温度范围广等。
因此，74HC系列芯片在数字系统和电子设备中得到了广泛应用。
74HC系列芯片具有多种功能，包括逻辑门、锁存器、计数器、选择器、多路复用器、分频器等。
这些功能不同的芯片可以满足不同的应用需求。
下面将对几个常用的74HC系列芯片进行介绍。
1. 74HC00：74HC00是一个四个二输入与门芯片。
它可以执行逻辑与操作，并且输出可以与其他逻辑门级联实现更复杂的逻辑功能。
该芯片通常用作数字系统中的数据选择器、信号触发器等。
2. 74HC08：74HC08是一个四个二输入与非门芯片。
与逻辑与门不同，逻辑与非门的输出是逻辑与门输出的反相信号。
该芯片可用于数字系统中的布尔代数运算、信号解码和数据传输等。
3. 74HC138：74HC138是一个三线到八线译码器/多路复用器。
它具有三个输入线和八个输出线，可以通过输入控制信号将一个特定的输出线与输入线相连。
该芯片常用于十进制数据的显示、地址解码和选择器等应用。
4. 74HC595：74HC595是一个八位移位寄存器。
它可以将数据按照指定的顺序移位存储，并通过串行输入和并行输出的方式与其他逻辑门级联。
该芯片常用于扩展I/O端口、控制LED 显示、驱动数码管等应用。
5. 74HC4040：74HC4040是一个二进制计数器。
它具有十二个计数位和一个异步复位端口，可以按照特定的时钟信号进行二进制计数，并通过输出端口显示计数值。
该芯片广泛应用于时序控制、频率分频器等数字电路中。
除了上述常用的74HC系列芯片，还有许多其他功能的芯片，如74HC04（六个反相器）、74HC14（六个反相器带施密特触发器）等。
这些芯片以其高性能、低功耗、多功能的特点，为数字系统和电子设备的设计者提供了灵活性和便利性。
74HC系列芯片的区别
74HC/LS/HCT/F系列芯片的区别1、LS是低功耗肖特基，HC是高速COMS。
LS的速度比HC略快。
HCT输入输出与LS兼容，但是功耗低；F是高速肖特基电路；2、LS是TTL电平，HC是COMS电平。
3、LS输入开路为高电平，HC输入不允许开路，hc 一般都要求有上下拉电阻来确定输入端无效时的电平。
LS 却没有这个要求4、LS输出下拉强上拉弱，HC上拉下拉相同。
5、工作电压不同，LS只能用5V，而HC一般为2V到6V；6、电平不同。
LS是TTL电平，其低电平和高电平分别为0.8和V2.4，而CMOS在工作电压为5V时分别为0.3V和3.6V，所以CMOS可以驱动TTL，但反过来是不行的7、驱动能力不同，LS一般高电平的驱动能力为5mA，低电平为20mA；而CMOS的高低电平均为5mA；8、CMOS器件抗静电能力差，易发生栓锁问题，所以CMOS的输入脚不能直接接电源。
74系列集成电路大致可分为6大类：. 74××（标准型）；.74LS××（低功耗肖特基）；.74S××（肖特基）；.74ALS××（先进低功耗肖特基）；.74AS××（先进肖特基）；.74F××（高速）。
近年来还出现了高速CMOS电路的74系列，该系列可分为3大类：. HC为COMS工作电平；. HCT为TTL工作电平，可与74LS系列互换使用；.HCU适用于无缓冲级的CMOS电路。
这9种74系列产品，只要后边的标号相同，其逻辑功能和管脚排列就相同。
根据不同的条件和要求可选择不同类型的74系列产品，比如电路的供电电压为3V就应选择74HC系列的产品系列电平典型传输延迟ns 最大驱动电流(-Ioh/Lol)mAAHC CMOS 8.5 -8/8AHCT COMS/TTL 8.5 -8/8HC COMS 25 -8/8HCT COMS/TTL 25 -8/8ACT COMS/TTL 10 -24/24F TTL 6.5 -15/64ALS TTL 10 -15/64LS TTL 18 -15/24LVCACSLC注：同型号的74系列、74HC系列、74LS系列芯片，逻辑功能上是一样的。

功率多谐振荡器电路
功率多谐振荡器电路
1．用途●逆变电源。
2．原理
●电路如图1. 22所示。
这个简单的多谐振荡器具有极高的效率和很强的负载驱动能力，74HC126D 它输出一个幅度接近于电源电压的对称矩形波。
多谐振荡器由Ts、T6、Ri、Rz、C．和C7组成。
●Ts和T6的集电极电流分别驱动Ti和Tz，其发射极电流则分别驱动T3和T4，电流的极限值由R．(R4)而决定。
●值得注意的是，晶体管的电流可能相对高，其值是晶体管的电流放大系数，如图1.22所示，
R=6801,，多谐振荡器的输出电流可达3A。
●振荡器的输出频率近似，其220tlF，Ub =12V时，振荡频率大约为53Hz。
该电路的应用之一是用于直流逆变电源，振荡器的输出连接到逆变变压器的低压端。
●图1.22所示的原型电路在振荡频率为50Hz[Ri一33Q,，R2 =34k（两个68kCl,并联），C=
440ruF（两个220VF并联）]时，输出电流相当大。
连接到9.5V／220V、5A的变压器，输出近240V的矩形波电压，输出功率可达40W。
●电路的静止电流损牦由Ri决定，该测试电路电流约为0.3A。
●当多谐振荡器驱动一个感性负载的时候，每个输出三极管一定在集电极与发射极之间接一个反向的快速大电流二极管，消除自感电动势，保护晶体三极管。

The 3-state outputs (nY) are controlled by the output enable input (nOE). A LOW at nOE causes the outputs to assume a HIGH impedance OFF-state.The “126”is identical to the “125” but has active HIGH enable inputs.QUICK REFERENCE DATAGND = 0 V; T amb = 25°C; t r = t f = 6 ns Notes1.C PD is used to determine the dynamic power dissipation (P D in µW):P D = C PD ×V CC 2×f i +∑(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∑(C L ×V CC 2×f o )= sum of outputs2.For HC the condition is V I = GND to V CCFor HCT the condition is V I = GND to V CC ?1.5 V ORDERING INFORMATIONSee “74HC/HCT/HCU/HCMOS Logic Package Information”.SYMBOL PARAMETERCONDITIONS TYPICAL UNIT HCHCTt PHL / t PLH propagation delay nA to nY C L = 15 pF; V CC = 5 V911ns C I input capacitance3.5 3.5pF C PD power dissipation capacitance per buffernotes 1 and 22324pFPIN DESCRIPTIONPIN NO.SYMBOL NAME AND FUNCTION1, 4, 10, 131OE to 4OE output enable inputs (active HIGH)2, 5, 9, 121A to 4A data inputs3, 6, 8, 111Y to 4Y data outputs7GND ground (0 V)14V CC positive supply voltageFig.1 Pin configuration.Fig.2 Logic symbol.Fig.3 IEC logic symbol.(a)(b)Fig.4 Functional diagram.Fig.5 Logic diagram(one buffer).FUNCTION TABLENote1.H = HIGH voltage levelL = LOW voltage levelX = don’t careZ = high impedance OFF-stateINPUTS OUTPUT nOE nA nYHHLLHXLHZDC CHARACTERISTICS FOR 74HCFor the DC characteristics see“74HC/HCT/HCU/HCMOS Logic Family Specifications”.

1. General description
The 74HC126; 74HCT126 is a quad buffer/line driver with 3-state outputs controlled by the output enable inputs (nOE). A LOW on nOE causes the outputs to assume a high-impedance OFF-state. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.
