本软件是关于MAX338, MAX339的英文数据手册：MAX338, MAX339 8通道/双4通道、低泄漏、CMOS模拟多路复用器 The MAX338/MAX339 are monolithic, CMOS analog multiplexers (muxes). The 8-channel MAX338 is designed to connect one of eight inputs to a common output by control of a 3-bit binary address. The dual, 4-channel MAX339 is designed to connect one of four inputs to a common output by control of a 2-bit binary address. Both devices can be used as either a mux or a demux. On-resistance is 400Ω max, and the devices conduct current equally well in both directions. These muxes feature extremely low off leakages (less than 20pA at +25°C), and extremely low on-channel leakages (less than 50pA at +25°C). The new design offers guaranteed low charge injection (1.5pC typ) and electrostatic discharge (ESD) protection greater than 2000V, per method 3015.7. These improved muxes are pin-compatible upgrades for the industry-standard DG508A and DG509A. For similar Maxim devices with lower leakage and charge injection but higher on-resistance, see the MAX328 and MAX329.

It would not be an exaggeration to say that semiconductor devices have transformed humanlife. From computers to communications to internet and video games These devices and the technologies they have enabled have expanded human experience in a way that is unique in history. Semiconductor devices have exploited materials, physics and imaginative applications to spawn new lifestyles. Of course for the device engineer, in spite of the advances, the challenges of reaching higher frequency, lower power consumption, higher power generation etc.

This book evolved over the past ten years from a set of lecture notes developed while teaching the undergraduate Algorithms course at Berkeley and U.C. San Diego. Our way of teaching this course evolved tremendously over These years in a number of directions, partly to address our students' background (undeveloped formal skills outside of programming), and partly to reect the maturing of the eld in general, as we have come to see it. The notes increasingly crystallized into a narrative, and we progressively structured the course to emphasize the story line implicit in the progression of the material. As a result, the topics were carefully selected and clustered. No attempt was made to be encyclopedic, and this freed us to include topics traditionally de-emphasized or omitted from most Algorithms books.

C++在几乎所有的计算环境中都非常普及，而且可以用于几乎所有的应用程序。C++从C中继承了过程化编程的高效性，并集成了面向对象编程的功能。C++在其标准库中提供了大量的功能。有许多商业C++库支持数量众多的操作系统环境和专业应用程序。但因为它的内容太多了，所以掌握C++并不十分容易。本书详述了C++语言的各个方面，包括数据类型、程序控制、函数、指针、调试、类、重载、继承、多态性、模板、异常和输入输出等内容。每一章都以前述内容为基础，每个关键点都用具体的示例进行详细的讲解。本书基本不需要读者具备任何C++知识，书中包含了理解C++的所有必要知识，读者可以从头开始编写自己的C++程序。本书也适合于具备另一种语言编程经验但希望全面掌握C++语言的读者。 I created all the files under Microsoft Windows so lines are terminated by CR/LF. In addition to this "ReadMe" file you will find three zip archives in the primary archive, so you need to unzip each of These to get at the code. 为PDG格式,这有pdg阅读器下载|pdg文件阅读器下载

This white paper discusses how market trends, the need for increased productivity, and new legislation have accelerated the use of safety systems in industrial machinery. This TÜV-qualified FPGA design methodology is changing the paradigms of safety designs and will greatly reduce development effort, system complexity, and time to market. This allows FPGA users to design their own customized safety controllers and provides a significant competitive advantage over traditional microcontroller or ASIC-based designs. Introduction The basic motivation of deploying functional safety systems is to ensure safe operation as well as safe behavior in cases of failure. Examples of functional safety systems include train brakes, proximity sensors for hazardous areas around machines such as fast-moving robots, and distributed control systems in process automation equipment such as those used in petrochemical plants. The International Electrotechnical Commission’s standard, IEC 61508: “Functional safety of electrical/electronic/programmable electronic safety-related systems,” is understood as the standard for designing safety systems for electrical, electronic, and programmable electronic (E/E/PE) equipment. This standard was developed in the mid-1980s and has been revised several times to cover the technical advances in various industries. In addition, derivative standards have been developed for specific markets and applications that prescribe the particular requirements on functional safety systems in These industry applications. Example applications include process automation (IEC 61511), machine automation (IEC 62061), transportation (railway EN 50128), medical (IEC 62304), automotive (ISO 26262), power generation, distribution, and transportation. 图Figure 1.

Introduction to Xilinx Packaging Electronic packages are interconnectable housings for semiconductor devices. The major functions of the electronic packages are to provide electrical interconnections between the IC and the board and to efficiently remove heat generated by the device. Feature sizes are constantly shrinking, resulting in increased number of transistors being packed into the device. Today's submicron technology is also enabling large-scale functional integration and system-on-a-chip solutions. In order to keep pace with These new advancements in silicon technologies, semiconductor packages have also evolved to provide improved device functionality and performance. Feature size at the device level is driving package feature sizes down to the design rules of the early transistors. To meet These demands, electronic packages must be flexible to address high pin counts, reduced pitch and form factor requirements. At the same time,packages must be reliable and cost effective.

Design techniques for electronic systems areconstantly changing. In industries at the heart of thedigital revolution, this change is especially acute.Functional integration, dramatic increases incomplexity, new standards and protocols, costconstraints, and increased time-to-market pressureshave bolstered both the design challenges and theopportunities to develop modern electronic systems.One trend driving These changes is the increasedintegration of core logic with previously discretefunctions to achieve higher performance and morecompact board designs.
