Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

我最近在《华尔街日报》看到一篇题为“我们需要能维修自己的电子小玩意儿的权利(We need the right to repair our gadgets)”的文章(参考原文：)，作者对于众多电子产品看来是“有计画的废弃(planned obsolescence)”之现象非常愤怒，认为大众应该要求电子产品可以被维修。 但实际的情况是，举例来说，家家都有的电视机如果故障了，修理费用可能...[详细]
