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。

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

74系列的参数
随着集成电路技术和工艺飞速发展， TTL74LS00系列和CMOS4000系列作为逻辑控制电路比较完善，在自动控制、 家用电器制造、计算机应用、无线电通信、机电一体化工程领域获得了广泛的应用。
对于电子工程技术人员，有必要 了解这类集成电路的特性及功能，甚至需要获得其详细的技术手册，以满足工作的需求。
我们在这里对这类常用的集 成电路进行了汇编，并对其主要的功能框图或真值表进行了介绍，以方便大家查阅。

电容的取值与越小越好为原则，电容量太大，会对其工作速度构成影响。

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

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

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
