74HC245详细中文资料74HC245是一款高速CMOS器件，74HC2 45引脚兼容低功耗肖特基TTL（LSTTL）系列。

74HC245译码器可接受3位二进制加权地址输入（A0, A1和A2），并当使能时，提供8个互斥的低有效输出（Y0至Y7）。

74HC245特有3个使能输入端：两个低有效（E1和E2）和一个高有效（E3）。

除非E1和E2置低且E3置高，否则74HC138将保持所有输出为高。

利用这种复合使能特性，仅需4片7 4HC245芯片和1个反相器，即可轻松实现并行扩展，组合成为一个1-32（5线到32线）译码器。

任选一个低有效使能输入端作为数据输入，而把其余的使能输入端作为选通端，则74HC245亦可充当一个8输出多路分配器，未使用的使能输入端必须保持绑定在各自合适的高有效或低有效状态。

74HC245与74HC 238逻辑功能一致，只不过74HC138为反相输出。

功能CD74HC245 ，CD74HC238和CD74HCT245， CD74HCT238是高速硅栅CMO S解码器，适合内存地址解码或数据路由应用。

74HC245作用原理于高性能的存贮译码或要求传输延迟时间短的数据传输系统,在高性能存贮器系统中,用这种译码器可以提高译码系统的效率。

将快速赋能电路用于高速存贮器时,译码器的延迟时间和存贮器的赋能时间通常小于存贮器的典型存取时间,这就是说由肖特基钳位的系统译码器所引起的有效系统延迟可以忽略不计。

HC138 按照三位二进制输入码和赋能输入条件,从8 个输出端中译出一个低电平输出。

两个低电平有效的赋能输入端和一个高电平有效的赋能输入端减少了扩展所需要的外接门或倒相器,扩展成24 线译码器不需外接门;扩展成32 线译码器,只需要接一个外接倒相器。

在解调器应用中,赋能输入端可用作数据输入端。

Each of the decoded outputs normally is lowand sequentially goes high on the low-to-high transition clock period of the ten-clock-period cycle. The carry (TC) output transitions low to high after output 9 goes from high to low, and can be used in conjunction with the clock enable (CE) input to cascade several stages. CE disables counting when in the high state. A master reset (MR) input also is provided that, when taken high, sets all the decoded outputs, except output 0, to low.The device can drive up to ten low-power Schottky equivalent loads.ORDERING INFORMATION {T APACKAGE ‡ORDERABLEPART NUMBER TOP-SIDE MARKING 40°C to 125°CSOIC − MTape and reelCD74HC4017QM96Q1HC4017Q −40C to 125TSSOP − PW Tape and reelCD74HC4017QPWRQ1HC4017Q†For the most current package and ordering information, see the Package Option Addendum at the end of this document, or see the TI web site at .‡Package drawings, thermal data, and symbolization are available at /packaging.FUNCTION TABLEINPUTS OUTPUT STATE CP CE MR OUTPUT STATE †L X L No change X H L No change X X H 0 = H, 1−9 = L ↑L L Increments counter↓X L No change X ↑L No change H↓LIncrements counterNOTE:H = high voltage level, L = low voltage level,X = don’t care, ↑ = transition from low to high level, ↓ = transition from high to low level†If n < 5, TC = H, otherwise TC = LPRODUCTION DATA information is curre nt as of publication date .Products conform to specifications per the terms of Texas Instruments standard warranty.

74LS系列与74HC，74HCT，CD系列的区别一、概述：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/74vHC--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”。

二、TTL逻辑芯片与与CMOS逻辑芯片的区别1.TTL工作电压范围为5V正负左右。

CMOS为3--18V左右。

2.频率特性：标准TTL电路在5MHZ以下，一般COMS在100KHZ以下。

3.速度*功耗积：（在100KHZ时，单位为PJ）标准TTL电路和为100。

标准CMOS为11。

4.最小输出的驱动电流（单位MA，输出低电平0.4V）标准输出：标准TTL系列为16。

标准COMS（4000系列为16，74系列为4）。

5.大电流输出：标准TTL为48V。

标准COMS（4000为16，74系列为6）6.扇出能力：标准TTL为系列为40（大电流输出为120）。

标准COMS（4000系列为4，74系列为10，大电流输出为4，15）。

7.最大输入电流（单位MA，输出低电平4V）：标准TTL系列为-1.6。

COMS（4000系列为正负0.001，74系列为负0.001）。

8.输入阻抗：COMS可达10M，TTL为5M。

74LSHC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。

2.HC上拉下拉能力相同，LS上拉弱而下拉强。

3.输入特性不同:HC输入电阻很高，输入开路时电平不定。
