(1) The marketing status values are defined as follows:

ACTIVE: Product 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: 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 https://www.360docs.net/doc/a918398811.html,/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.

(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. If a line is indented then it is a continuation of the previous line and the two combined represent the entire Device Marking for that device.

(6) Lead/Ball Finish - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finish value exceeds the maximum column width.

74LS373详细资料精心整理

74LS373 引脚图、内部结构、参数、典型应用电路【功能简介】 74LS373是一款常用的地址锁存器芯片，由八个并行的、带三态缓冲输出的D触发器构成。在单片机系统中为了扩展外部存储器，通常需要一块74LS373芯片。本文将介绍74LS373的工作原理，内容涵盖引脚图、内部结构、主要参数以及在单片机扩展系统中的典型应用电路。【内部逻辑结构图】 74LS373地址锁存器的内部逻辑结构如图一所示。图1

【74LS373的真值表(功能表)】 G—与8031/8051的ALE相连，控制八个D型锁存器的导通与截止：高电平时，八个D型锁存器正常运行（导通），即锁存器的输出端与输入端D的反相信号始终同步；低电平时锁存器截止，D锁存器输出端的状态保持不变。 OE（Output Enable = Output Control）—使能端，接地时锁存【74LS373引脚排列图】

【74LS373电气参数】拖动图片放大！ 74ls373推荐工作条件【74LS373在单片机扩展系统中的典型应用电路】当74LS373用作地址锁存器时，应使OE为低电平，此时锁存使能端G为高电平时，输出Q0-Q7的状态与输入端D1-D7状态相同；当G发生负的跳变时，输入端D0-D7 数据锁入Q0-Q7。51单片机的ALE信号可以直接与74LS373的G 连接。在MCS-51单片机系统中，其连接方法如下图所示。其中输入端1D-8D接

至单片机的P0口，输出端提供的是低8位地址，G端接至单片机的地址锁存允许信号ALE。输出允许端OE接地，表示三态输出门一直导通，可以送出地址信号。 1D-8D为8个输入端。 1Q-8Q为8个输出端。【说明】基础比较好的同学请直接忽略。 G是数据锁存控制端；当G=1时，锁存器输出端同输入端；当G由“1”变为“0”时，数据输入锁存器中。 OE为输出允许端；当OE=“0”时，三态门打开；当OE=“1”时，三态门关闭，输出呈高阻状态。 (1).1脚是输出使能(OE),是低电平有效,当1脚是高电平时,不管输入3、4、7、8、13、14、17、18如何,也不管11脚(锁存控制端,G)如何,输出2(Q0)、5(Q1)、6(Q2)、9(Q3)、12(Q4)、15(Q5)、16(Q6)、19(Q7)全部呈现高阻状态(或者叫浮空状态); (2).当1脚是低电平时,只要11脚(锁存控制端,G)上出现一个下降沿,输出2(Q0)、5(Q1)、6(Q2)、9(Q3)、12(Q4)、15(Q5)、16(Q6)、19(Q7)立即呈现输入脚3、4、7、8、13、14、17、18的状态. 锁存端LE 由高变低时，输出端8 位信息被锁存，直到LE 端再次有效。当三态门使能信号OE为低电平时，三态门导通，允许Q0~Q7输出，OE为高电平时，输出悬空。

74LS系列芯片简介

红色标记为实验室有的芯片 74系列芯片的型号区别与功能略表 2010-05-31 16:39 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；而HCT的工作电压一般为4.5V～5.5V。 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)mA AHC CMOS 8.5 -8/8 AHCT COMS/TTL 8.5 -8/8 HC COMS 25 -8/8 HCT COMS/TTL 25 -8/8 ACT COMS/TTL 10 -24/24 F TTL 6.5 -15/64 ALS TTL 10 -15/64 LS TTL 18 -15/24 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。 74LSxx的使用说明如果找不到的话，可参阅74xx或74HCxx的使用说明。有些资料里包含了几种芯片，如74HC161资料里包含了74HC160、74HC161、74HC162、74HC163四种芯片的资料。找不到某种芯片的资料时，可试着查看一下临近型号的芯片资料。 74HC的速度比4000系列快，引脚与标准74系列兼容 4000系列的好处是有的型号可工作在+15V 。新产品最好不用LS。https://www.360docs.net/doc/a918398811.html, 功能略表 74HC01 2输入四与非门 (oc) 74HC02 2输入四或非门 74HC03 2输入四与非门 (oc) 74HC04 六倒相器 74HC05 六倒相器(oc) 74HC06 六高压输出反相缓冲器/驱动器(oc,30v) 74HC07 六高压输出缓冲器/驱动器(oc,30v) 74HC08 2输入四与门 74HC09 2输入四与门(oc) 74HC10 3输入三与非门 74HC11 3输入三与门 74HC12 3输入三与非门 (oc)
