74HC373中文资料

74HC373中文资料

74HC373和74LS373原理一样,8数据锁存器。

主要用于数码管、按键等等的控制1. 真值表Dn LE OE OnH H L HL H L LX L L QoX X H Z这个就是真值表,表示这个芯片在输入和其它的情况下的输出情况。

每个芯片的数据手册(datasheet)中都有真值表。

布尔逻辑比较简单,在此不赘述;2. 高阻态就是输出既不是高电平,也不是低电平,而是高阻抗的状态;在这种状态下,可以多个芯片并联输出;但是,这些芯片中只能有一个处于非高阻态状态,否则会将芯片烧毁; 高阻态的概念在RS232和RS422通讯中还可以用到。

3. 数据锁存当输入的数据消失时,在芯片的输出端,数据仍然保持;这个概念在并行数据扩展中经常使用到。

4. 数据缓冲加强驱动能力。

74LS244/74LS245/74LS373/74LS573都具备数据缓冲的能力。

OE:output_enable,输出使能;LE:latch_enable,数据锁存使能,latch是锁存的意思;Dn:第n路输入数据;On:第n路输出数据;再看这个真值表,意思如下:第四行:当OE=1是,无论Dn、LE为何,输出端为高阻态;第三行:当OE=0、LE=0时,输出端保持不变;第二行第一行:当OE=0、LE=1时,输出端数据等于输入端数据;结合下面的波形图,在实际应用的时候是这样做的:a.OE=0;b.先将数据从单片机的口线上输出到Dn;c.再将LE从0->1->0d.这时,你所需要输出的数据就锁存在On上了,输入的数据在变化也影响不到输出的数据了;实际上,单片机现在在忙着干别的事情,串行通信、扫描键盘……单片机的资源有限啊。

在单片机按照RAM方式进行并行数据的扩展时,使用movx @dptr, A这条指令时,这些时序是由单片机来实现的。

后面的表格中还有需要时间的参数,你不需要去管它,因为这些参数都是几十ns级别的,对于单片机在12M下的每个指令周期最小是1us的情况下,完全可以实现;如果是你自己来实现这个逻辑,类似的指令如下:mov P0,A ;将数据输出到并行数据端口clr LEsetb LEclr LE ;上面三条指令完成LE的波形从0->1->0的变化74ls573跟74LS373逻辑上完全一样,只不过是管脚定义不一样,数据输入和输出端。

74HC373; 74HCT373Octal D-type transparent latch; 3-stateRev. 4 — 3 September 2010Product data sheet1. General descriptionThe 74HC373; 74HCT373 is a high-speed Si-gate CMOS device and is pin compatiblewith Low-power Schottky TTL. It is specified in compliance with JEDEC standard no. 7A.The 74HC373; 74HCT373 is an octal D-type transparent latch featuring separate D-typeinputs for each latch and 3-state outputs for bus oriented applications. A latch enable (LE)input and an output enable (OE) input are common to all latches.The 74HC373; 74HCT373 consists of eight D-type transparent latches with 3-state trueoutputs. When LE is HIGH, data at the Dn inputs enters the latches. In this condition thelatches are transparent, i.e. a latch output will change state each time its correspondingD input changes.When LE is LOW the latches store the information that was present at the D inputs aset-up time preceding the HIGH-to-LOW transition of LE. When OE is LOW, the contentsof the 8 latches 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 latches.The 74HC373; 74HCT373 is functionally identical to:•74HC563; 74HCT563: but inverted outputs and different pin arrangement•74HC573; 74HCT573: but different pin arrangement2. Features and benefits3-state non-inverting outputs for bus oriented applicationsCommon 3-state output enable inputFunctionally identical to the 74HC563; 74HCT563 and 74HC573; 74HCT573ESD protection:HBM JESD22-A114F exceeds 2000VMM JESD22-A115-A exceeds 200VSpecified from −40°C to+85°C and from −40°C to+125°C3.
