TRANSLATION AND 3-STATE OUTPUTSSCES515H–DECEMBER 2003–REVISED JANUARY 2007The SN74LVC1T45is designed for asynchronous communication between two data buses.The logic levels of the direction-control (DIR)input activate either the B-port outputs or the A-port outputs.The device transmits data from the A bus to the B bus when the B-port outputs are activated and from the B bus to the A bus when the A-port outputs are activated.The input circuitry on both A and B ports always is active and must have a logic HIGH or LOW level applied to prevent excess I CC and I CCZ .The SN74LVC1T45is designed so that the DIR input is powered by V CCA .This device is fully specified for partial-power-down applications using I off .The I off circuitry disables the outputs,preventing damaging current backflow through the device when it is powered down.The V CC isolation feature ensures that if either V CC input is at GND,then both ports are in the high-impedance state.NanoFree™package technology is a major breakthrough in IC packaging concepts,using the die as the package.FUNCTION TABLE (1)INPUT OPERATION DIR L B data to A bus HA data toB bus(1)Input circuits of the data I/Os always are active.LOGIC

TRANSCEIVERWITH CONFIGURABLE VOLTAGE TRANSLATION AND 3-STATE OUTPUTSSCES515H–DECEMBER 2003–REVISED JANUARY 2007Figure 3shows the SN74LVC1T45being used in a bidirectional logic level-shifting application.Since the SN74LVC1T45does not have an output-enable (OE)pin,the system designer should take precautions to avoid bus contention between SYSTEM-1and SYSTEM-2when changing directions.The following table shows data transmission from SYSTEM-1to SYSTEM-2and then from SYSTEM-2to SYSTEM-1.STATE DIR CTRLI/O-1I/O-2DESCRIPTION1H Out In SYSTEM-1data to SYSTEM-2SYSTEM-2is getting ready to send data to SYSTEM-1.I/O-1and I/O-2are disabled.The 2H Hi-Z Hi-Z bus-line state depends on pullup or pulldown.(1)DIR bit is flipped.I/O-1and I/O-2still are disabled.The bus-line state depends on pullup or

ApplicationCalculate the enable times for the SN74LVC1T45using the following formulas:•t PZH (DIR to A)=t PLZ (DIR to B)+t PLH (B to A)•t PZL (DIR to A)=t PHZ (DIR to B)+t PHL (B to A)•t PZH (DIR to B)=t PLZ (DIR to A)+t PLH (A to B)•t PZL (DIR to B)=t PHZ (DIR to A)+t PHL (A to B)In a bidirectional application,these enable times provide the maximum delay from the time the DIR bit is switched until an output is expected.For example,if the SN74LVC1T45initially is transmitting from A to B,then the DIR bit is switched;the B port of the device must be disabled before presenting it with an input.After the B port has been disabled,an input signal applied to it appears on the corresponding A port after the specified propagation delay.PACKAGING INFORMATIONOrderable Device Status (1)Package

74HC154 功能简述:
74HC154 4线-16 线译码器/解调器
·将4个二进制编码输入译成16个彼独立的输出之一
·将数据从一个输入线分配到16个输出的任意一个而实现解调功能·输入箝位二极管简化了系统设计
·与大部分TTL和DTL电路完全兼容
74154这种单片4 线—16 线译码器非常适合用于高性能存储器的译码器。
当两个选通输入G1 和G2 为低时, 它可将4 个二进制编码的输入译成16 个互相独立的输出之一。
实现解调功能的办法是：用4 个输入线写出输出线的地址，使得在一个选通输入为低时数据通过另一个选通输入。
当任何一个选通输入是高时，所有输出都为高。

74sl151(详细)
8选1数据选择器74LS151（151 为互补输出的8 选1 数据选择器）74LS151为互补输出的8选1数据选择器，引脚排列如图所示，功能见表。
引脚，又叫管脚，英文叫Pin。
就是从集成电路（芯片）内部电路引出与外围电路的接线，所有的引脚就构成了这块芯片的接口数据选择端（ABC）按二进制译码（译码是编码的逆过程，同时去掉比特流在传播过程中混入的噪声。
利用译码表把文字译成一组组数码或用译码表将代表某一项信息的一系列信号译成文字的过程称之为译码。
），以从8 个数据（D0---D7）中选取1 个所需的数据。
只有在选通端STROBE 为低电平时才可选择数据。
151 有互补输出端（Y、W），Y 输出原码，W 输出反码。
选择控制端（地址端）为C～A，按二进制译码，从8个输入数据D0～D7中，选择一个需要的数据送到输出端Y，G为使能端，低电平有效。
(就是说能使芯片工作的端口，如果使能端开，芯片就能工作，一般你看表示使能端的符号，如果上面有一横就是低电平有效（即如果使能端为低电平，芯片就能工作），反之就是高电平有效。
)又叫使能输入端（enable），它是芯片的一个输入引脚，或者电路的一个输入端口，只有该引脚激活，芯片才能工作，通常情况下为高电平有效，若符号上面有一横，则表示低电平有效。
多路选择器多路选择器是数据选择器的别称。
在多路数据传送过程中，能够根据需要将其中任意一路选出来的电路，叫做数据选择器，也称多路选择器或多路开关。
有4选1数据选择器、8选1数据选择器（型号为74151、74LS151、74251、74LS151）、16选1数据选择器（可以用两片74151连接起来构成）等之分。
多路选择器还包括总线的多路选择,模拟信号的多路选择等,相应的器件也有不同的特性和使用方法.具体可以查找相关网站数据选择器的定义及功能数据选择是指经过选择，把多个通道的数据传送到唯一的公共数据通道上去。
（1）使能端G＝1时，不论C～A状态如何，均无输出（Y＝0，W＝1），多路开关被禁止。

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74HC属于CMOS系列，输入阻抗高，输出电压高（4.9V为逻辑1），驱动能力差；74LS属于TTL系列，输出电压较低（3.5V为逻辑1），驱动能力较强；与单片机匹配，关系不大，但尽量用同一类型的芯片，即74HC 系列74系列芯片功能大全7400 TTL 2输入端四与非门7401 TTL

TRANSLATION AND 3-STATE OUTPUTSSCES515H–DECEMBER 2003–REVISED JANUARY 2007The SN74LVC1T45is designed for asynchronous communication between two data buses.The logic levels of the direction-control (DIR)input activate either the B-port outputs or the A-port outputs.The device transmits data from the A bus to the B bus when the B-port outputs are activated and from the B bus to the A bus when the A-port outputs are activated.The input circuitry on both A and B ports always is active and must have a logic HIGH or LOW level applied to prevent excess I CC and I CCZ .The SN74LVC1T45is designed so that the DIR input is powered by V CCA .This device is fully specified for partial-power-down applications using I off .The I off circuitry disables the outputs,preventing damaging current backflow through the device when it is powered down.The V CC isolation feature ensures that if either V CC input is at GND,then both ports are in the high-impedance state.NanoFree™package technology is a major breakthrough in IC packaging concepts,using the die as the package.FUNCTION TABLE (1)INPUT OPERATION DIR L B data to A bus HA data toB bus(1)Input circuits of the data I/Os always are active.LOGIC

ApplicationCalculate the enable times for the SN74LVC1T45using the following formulas:•t PZH (DIR to A)=t PLZ (DIR to B)+t PLH (B to A)•t PZL (DIR to A)=t PHZ (DIR to B)+t PHL (B to A)•t PZH (DIR to B)=t PLZ (DIR to A)+t PLH (A to B)•t PZL (DIR to B)=t PHZ (DIR to A)+t PHL (A to B)In a bidirectional application,these enable times provide the maximum delay from the time the DIR bit is switched until an output is expected.For example,if the SN74LVC1T45initially is transmitting from A to B,then the DIR bit is switched;the B port of the device must be disabled before presenting it with an input.After the B port has been disabled,an input signal applied to it appears on the corresponding A port after the specified propagation delay.PACKAGING INFORMATIONOrderable Device Status (1)Package
