74系列集成电路的分类及区别2008-12-26 13:42:44| 分类：默认分类| 标签：|字号大中小订阅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）。

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。

补充:．74 –系列这是早期的产品，现仍在使用，但正逐渐被淘汰。

2．74H –系列这是74 –系列的改进型，属于高速TTL产品。

其“与非门”的平均传输时间达10ns左右，但电路的静态功耗较大，目前该系列产品使用越来越少，逐渐被淘汰。

3．74S –系列这是TTL的高速型肖特基系列。

在该系列中，采用了抗饱和肖特基二极管，速度较高，但品种较少。

4．74LS –系列这是当前TTL类型中的主要产品系列。

品种和生产厂家都非常多。

性能价格比比较高，目前在中小规模电路中应用非常普遍。

5．74ALS –系列这是“先进的低功耗肖特基”系列。

属于74LS –系列的后继产品，速度（典型值为4ns）、功耗（典型值为1mW）等方面都有较大的改进，但价格比较高。

6．74AS –系列这是74S –系列的后继产品，尤其速度（典型值为1.5ns）有显著的提高，又称“先进超高速肖特基”系列。

7．74HC –系列54/74HC –系列是高速CMOS标准逻辑电路系列，具有与74LS –系列同等的工作度和CMOS集成电路固有的低功耗及电源电压范围宽等特点。

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 page

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

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

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: TI has discontinued the production of the device.(2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may reference these types of products as "Pb-Free".RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption.Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of <=1000ppm threshold. Antimony trioxide based flame retardants must also meet the <=1000ppm threshold requirement.Addendum-Page 1(3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.(4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.(5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device.
