5474系列逻辑芯片

5474系列逻辑芯⽚
1 54/74系列电路是数字电路常⽤的逻辑电路.54是军标的，74是民⽤商⽤的，但其电路功能相同。

2 LS输⼊开路是⾼电平，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，⽽LS却没有这个要求。

3 LS下拉强上拉弱，HC上拉下拉相同；(理解是驱动电流的强弱）
4 ⼯作电压不同，LS只能⽤5V，HC⼀般⽤2V⾄6V；
5 逻辑电平不同。

LS是TTL电平，其低电平⾼电平分界值分别为0.8V，2，4V；HC⼯作电压为5V时，低电平⾼电平分界值是0.3V与3.6V。

CMOS逻辑门电路可以驱动TTL逻辑门电路。

6 驱动能⼒不同。

LS⾼电平驱动能⼒⼀般是5mA，低电平时驱动能⼒是20mA；CMOS的⾼低电平驱动能⼒都是5mA
7 CMOS结构的电路抗静电能⼒差，容易发⽣栓锁问题，所以CMOS得输⼊脚不能接电源；
8 74系列分为TTL，CMOS两⼤类。

9 74 TTL类的有74XX（标准型）；74LSXX（低功耗肖特基型）；74SXX（肖特基型）；74ALSXX（先进低功耗肖特基型）；74ASXX(先进肖特基型)；74FXX(⾼速型)；
10 74系列⾼速CMOS分为3⼤类：74HCXX(CMOS⼯作电平)；74HCT(CMOS的TTL电平)；74HCUXX(⽆缓冲）;
11 74系列产品，若表⽰逻辑功能的数字相同，其功能相同。

12 若供电电压是3V，就应选择74HCXX型的；供电电压5V时，应选择74LSXX型的。

13 常⽤类型的典型电性参数值。

【74系列】74LS、74HC、CD系列的详细区别是什么？[修订]

【74系列】74LS、74HC、CD系列的详细区别是什么？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。

最佳答案74LS是TTL电路的一个系列，TTL电路以双极型晶体管为开关元件所以以称双极型（电子和空穴）集成电路。

74HC是CMOS电路，CMOS电路是MOS电路中的主导产品。

MOS电路以绝缘栅场效应晶体管为开关元件。

所以又称单极型集成电路。

按其导电沟道的类型，MOS电路可分为PMOST 、NMOS和CMOS电路。

CMOS电路沿着4000A--4000B/4500B（统一称为4000B）--74HC--74HCT系列高速发展。

HCT系列还同TTL电平兼容，扩大了应用范围。

CD代表标准的4000系列CMOS电路，我国生产的CMOS电路系列为“CC4000B”性能：TTL工作电压范围为5V正负左右。

CMOS为3--18V左右。

频率特性：标准TTL电路在5MHZ以下，一般COMS在100KHZ以下。

The Harris CD74HC32, CD74HCT32 contain four 2-input OR gates in one package. Logic gates utilize silicon gate CMOS technology to achieve operating speeds similar to LSTTL gates with the low power consumption of standard CMOS integrated circuits. All devices have the ability to drive 10 LSTTL loads. The 74HCT logic family is functionally pin compatible with the standard 74LS logic family.

20140918-关于逻辑芯片如74与54、LV与LVC、HC与HCT等区别

20140918-关于逻辑芯片如74与54、LV与LVC、HC与HCT等区别74系列与54系列：54系列的TTL电路和74系列的TTL电路具有完全相同的电路结构和电气参数，二者的差别仅为工作温度范围和电源电压范围。

54系列的工作温度范围为-55到+125摄氏度，电源电压范围为5V±10%。

74系列的工作温度范围为0到70摄氏度，电源电压范围为5V±5%。

以前经常说54系列是军品级，74是商业级，如54LS138和74LS138就是温度范围不一样。

NOTE: When ordering, use the entire part number. The sufﬁx 96 denotes tape and reel. The sufﬁx T denotes a small-quantity reel of 250.
• Wide Operating Temperature Range . . . -55oC to 125oC
The CD54HC00, CD74HC00, CD54HCT00, and CD74HCT00 logic gates utilize silicon gate CMOS technology to achieve operating speeds similar to LSTTL gates with the low power consumption of standard CMOS integrated circuits. All devices have the ability to drive 10 LSTTL loads. The 74HCT logic family is functionally pin compatible with the standard 74LS logic family.
• HC Types - 2V to 6V Operation - High Noise Immunity: NIL = 30%, NIH = 30% of VCC at VCC = 5V
• HCT Types - 4.5V to 5.5V Operation - Direct LSTTL Input Logic Compatibility, VIL= 0.8V (Max), VIH = 2V (Min) - CMOS Input Compatibility, Il ≤ 1µA at VOL, VOH

54及74系列电路知识

（1）对于各种集成电路，使用时一定要在推荐的工作条件范围内，否则将导致性能下降或损坏器件。（2）数字集成电路中多余的输入端在不改变逻辑关系的前提下可以并联起来使用，也可根据逻辑关系的要求接地或接高电平。TTL电路多余的输入端悬空表示输入为高电平；但CMOS电路，多余的输入端不允许悬空，否则电路将不能正常工作。
TTL 电平与与 CMOS 电平的区别
（1）TTL 高电平 3.6 - 5V ，低电平0 - 2.4V 。 CMOS 电平可达到 12V ， CMOS 电路输出高电平约为0.9Vcc ，而输出低电平约为 0.1Vcc 。（2）CMOS 集成电路电源电压可以在较大范围内变化，因而对电源的要求不像 TTL 集成电路那样严格。用TTL 电平他们就可以兼容。
TTL 和 CMOS 电路比较
TTL 电路是电流控制器件，而 CMOS电路是电压控制器件； TTL 电路的速度快，传输延迟时间短（ 5-10ns ），但是功耗大， CMOS 电路的速度慢，传输延迟时间长（ 25-50ns ），但功耗低。 CMOS 电路本身的功耗与输入信号的脉冲频率有关，频率越高，芯片越热，这是正常现象。
74系列 ( 0－70℃） 54系列（－55－125 ℃） ①74：标准系列，前面介绍的TTL门电路都属于74系列，其典型电路与非门的平均传输时间tpd＝10ns，平均功耗P＝10mW。 ②74H：高速系列，是在74系列基础上改进得到的，其典型电路与非门的平均传输时间tpd＝6ns，平均功耗P＝22mW。

3、门电路
用以实现基本逻辑运算和复合逻辑运算的单元电路。 Vo Vi
获得高、低电平的基本原理
TTL：晶体管-晶体管逻辑，速度快。 (标准,S,LS,AS,ALS,F) MOS：金属-氧化物-半导体逻辑，功耗低。 (PMOS,NMOS,CMOS) (HC,AHC,AC,HCT,ACT,AHCT,LV,LVC) ECL：发射极偶合逻辑，速度更快。系列：74系列、54系列、4000系列等。命名：如SN74LS00。 SN：生产厂标，Texas公司；74：系列号；LS：生产工艺；00：功能号，2输入端与非门。
