1.74hc541中文资料
74HC541 8路缓冲器/线路驱动器具备74HC240所有的功能，并且把输入引脚和输出引脚分布在封装的两边，这就极大方便了印刷电路板的布线。
74HC541的三态输出由一个两输入或非门控制。
当任一个输出使能端（OE1或OE2）为高时，八个输出端将进入高阻态。
74HC541器件的输出为原码数据。
该7HC/HCT54是八进制非反相缓冲器/线路，具有三态输出的驱动器。
三态输出是由输出使能输入OE1和OE2控制。
OEN高导致输出呈现高电平。
阻抗呈关闭状态，“541”与“540”相同，但具有非反相输出。

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

Samples may or may not be available.OBSOLETE: TI has 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 6 substances, 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 represents TI's knowledge and belief as of the date that it is provided.
