The SP486 and SP487 are low–power quad differential line drivers meeting RS-485 and RS-422 standards. The SP486 features a common driver enable control the SP487 provides independent driver enable controls for each pair of drivers. Both feature tri–state outputs and wide common–mode input range. Both are available in 16–pin plastic DIP and SOIC packages.

Managing Humans is a selection of the best essays from Michael Lopps web site, Rands In Repose. Drawing on Lopp s management experiences at Apple, Netscape, Symantec, and Borland, this book is full of stories based on companies in the Silicon Valley where people have been known to yell at each other. It is a place full of dysfunctional bright people who are in an incredible hurry to find the next big thing so they can strike it rich and then do it all over again. Among these people are managers, a strange breed of people who through a mystical organizational ritual have been given power over your future and your bank account. Whether you re an aspiring manager, a current manager, or just wondering what the heck a manager does all day, there is a story in this book that will speak to you. You will learn: * What to do when people start yelling at each other * How to perform a diving save when the best engineer insists on resigning * How to say "No" to the person who signs your paycheck

The AT24C512 provides 524,288 bits of serial electrically erasable and programmable read only memory (EEPROM) organized as 65,536 words of 8 bits each. The device鈥檚 cascadable feature allows up to four devices to share a common two-wire bus. The device is optimized for use in many industrial and commercial applications where lowpower and low-voltage operation are essential. The devices are available in spacesaving 8-pin PDIP, 8-lead EIAJ SOIC, 8-lead JEDEC SOIC, 8-lead TSSOP, 8-lead Leadless Array (LAP), and 8-lead SAP packages. In addition, the entire family is available in 2.7V (2.7V to 5.5V) and 1.8V (1.8V to 3.6V) versions.

第一代Sandstorm家族，与JTAG复用的GPIO可以直接配置。但是不够安全，意外的配置有可能导致JTAG连接失效。 对于第二代Fury和第三代DustDevil家族，由于GPIOLOCK等寄存器的保护，相关Pin默认为JTAG功能而不允许直接配置为GPIO功能。如果要想配置为GPIO功能，则必须首先执行解锁操作。 详见GPIO文档和例程。
