四通道I^2C多路复用器提供了地址扩展、总线缓冲和故障管理

引用

中国集成电路 2007年第2期16卷 86-89页

作者： john ziegler 凌特公司

随着数据处理、海量存储和通信系统的发展，用于传送诸如温度、扇速、系统电压和关键产品数据（VPD，例如：电路板标识）等信息的子系统尺寸和复杂程度成比例地增长。在这些信息的传送中。最常用的就是两线式串行总线，比如：I^2C或SMBus。

随着服务器系统的增长,包含控制电路用来监视服务器输入/输出卡的数量和复杂程度也同比增长。零停机时间系统要求用户将1/O卡插入带电的背板。虽然许多IC供应商已经开发出能够安全对电源和地线进行热插拔（HotSwapTM）的芯片,但是迄今为止,仍没有一个能在I2C和SMBus系统中实现系统数据（SDA）和系统时钟（SCL）线“热插拔”的单片解决方案。由于每个1/O卡的SDA和SCL电容直接加到这些系统的背板中。

近几十年来，油田工作者已经成功地使用了降顶点剂。然而，原油的专一性．添加剂的大量使用以及含蜡成分一直严重影响着化学防蜡添加剂的性能。本文讨论了影响原油防蜡添加剂性能以及原油专一性的各项因素，研究了防蜡添加剂的聚合物支架、悬链和分子量对冷流添加剂性能的作用。同时也介绍了不同溶剂、防蜡添加剂稀释程度及添加剂所起的作用。本文结尾得出结论：向原油中有效混合添加剂对降频点剂的性能起重要作用。使用混合抑制剂能克服原油专一性，可以处理蜡含量范围广的原油。
