Lightning And Ground Loop Damage To Multiplexers
White Papers RS-232 line drivers and receivers are made for voltages ranging from +15 volts to -15 volts. Voltages exceeding the 23 volt device limit can be induced and damage the RS-232 drivers and receivers. Excessive voltages can be caused by power surges...

Microprocessor Supervisors Offer Big Insurance In Small Packages
White Papers Supply voltages glitch up and down due to external-component loads, or they drift in and out of tolerance as the bus voltages fluctuate or system batteries begin to fail. The world throws a wide range of problems at microprocessor-system designers.

A DC-based Culture Is Growing.
Blog AC has the advantage of being transformed to higher voltages and transmitted at lower currents. LEDs are better than CFLs because they work at low voltages and contain no mercury. In 1880 approximately, Thomas Edison and George Westinghouse...

How To Make Hot Chips That Stay Cool
News Playing around with voltages is a good way to cut your losses in other ways. Feed low-speed circuits with low voltages, and their leakage goes down. Intel has its eyes set on processors in 2010 that run 100 times faster than the basic Pentium 4.
