74HC245详细中文资料

74HC245详细中文资料

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。

特性复合使能输入,轻松实现扩展兼容JEDEC标准no.7A 存储器芯片译码选择的理想选择低有效互斥输出 ESD保护 HBM EIA/JESD22-A114-C超过2000 V MM EIA/JESD22-A115-A超过200 V 温度范围 -40~+85 ℃ -40~+125 ℃多路分配功能74HC245是一款高速CMOS器件,74HC245引脚兼容低功耗肖特基T TL(LSTTL)系列。

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 /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.

SN74LVC2T45 DUALĆBIT DUALĆSUPPLY BUS TRANSCEIVER WITH CONFIGURABLE VOLTAGE TRANSLATION AND 3ĆSTATE OUTPUTS
SCES516E − DECEMBER 2003 − REVISED MAY 2004
SN74LVC2T45 DUALĆBIT DUALĆSUPPLY BUS TRANSCEIVER WITH CONFIGURABLE VOLTAGE TRANSLATION AND 3ĆSTATE OUTPUTS
description/ordering information (continued)
The SN74LVC2T45 is designed so that the DIR input circuit is supplied by VCCA. This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down. The VCC isolation feature ensures that if either VCC input is at GND, both ports are in the high-impedance state. NanoStar and NanoFree package technology is a major breakthrough in IC packaging concepts, using the die as the package.
