It is anon-inverting multiplexer. When the STROBEinput is held high selection of data is inhibited andall the outputs become low. The SELECTdecoding determines whether the A or B inputsget routed to their corresponding Y outputs.Power down protection is provided on all inputsand 0 to 7V can be accepted on inputs with noregard to the supply voltage. This device can beused to interface 5V to 3V. All inputs and outputsare equipped with protection circuits against staticdischarge, giving them 2KV ESD immunity andtransient excess voltage.74VHC157

NC7SB3157, FSA3157

Low Voltage SPDT Analog Switch or

2:1 Multiplexer/Demultiplexer Bus Switch

General Description

The NC7SB3157 or FSA3157 is a high performance, sin-

gle-pole/double-throw (SPDT) Analog Switch or 2:1 Mul-

tiplexer/Demultiplexer Bus Switch. The device is

fabricated with advanced sub-micron CMOS technology

to achieve high speed enable and disable times and low

On Resistance. The break before make select circuitry

prevents disruption of signals on the B Port due to both

switches temporarily being enabled during select pin

switching. The device is specified to operate over the

1.65 to 5.5V V

CC

operating range. The control input toler-

一、 搭建开发环境

工具：Eclipse

数据库：Oracle

安装NC模块并建立帐套用户。

1.1 安装和配置插件

首先下载nc.uap.mde系列插件，然后安装,安装即把插件直接考贝Eclipse的plugin目录下，由于Eclipse的bug，如果曾经安装过，请把configuration目录下的内容除了config.ini外其他文件都删除，在此启动Eclipse即可。

设置Window->Prefreence->MDE Development

NC Home：基础技术平台的运行环境根目录。

复选框：表示是否把模块的client下的类加入到构件路径。如果你的模块不依赖别的模块的客户端代码，请取消该选择。

Datasourse

DriverList：开发环境的配置信息(在配置时，要把其他的配置信息删除掉，只留下design)，关联文件在NC Home的\ierp\bin\prop.xml。 -`

Database Type：数据库类型，选择的是ORACLE11G。

ModuleSelection

NC模块勾选。

Client Connection

客户端连接配置，对应机器ip和端口。启动客户端时根据此处配置连接。

1.2 新建MDE项目

直接创建：FileNewProjectMDE DevelopmentModule project ，按照Wizard进行工作，开发一个新的工程

项目转化：方式为在一个非MDE工程中，右击工程，在弹出菜单中点击。

src/public：存放服务接口和实体类(VO)，前台调用后台文件的接口。

src/private：后台实现类。

src/client：前台UI

META-INF：配置文件

针对上面的卡法模式，我们规范一下代码的包结构：

➢ nc.itf.: 表示该模块定义的接口(public)

➢ nc.impl.：表示该模块定义的接口实现(private)
