Linear Techno1ogy公司最近推出的LT4300芯片可对送至和来自一个可热插拔组件的I~2C数据和时钟信号起缓冲作用。完成这一任务之所以困难,乃是因为这一集成电路必须双向工作,从而意味着你可以同时有效地双边驱动。然而,有时候情况就是这样,你可以用一个简单电路取代一个复杂电路,而性能不会有多大下降。例如,用几只晶体 Linear Technology recently introduced LT4300 chip can be sent to and from a hot-swappable components I ~ 2C data and clock signals from the buffer. The difficulty in accomplishing this task is because the integrated circuit must work in both directions, which means you can drive both sides efficiently and effectively at the same time. However, sometimes it is the case that you can replace a complex circuit with a simple circuit without much degradation in performance. For example, use a few crystals
