移动手机发展迅速,目前的2.5G手机以及正在研究的3G和4G手机在未来的两到三年将会提供更高的数据速率,增加更多的用户功能和存储器。所有这些都要求用最低的功耗,以延长电池充电的间隔。 为了配合这种发展趋势,快捷(Fairchild)在已有的单门、双门以及三门的逻辑功能电路基础上,开发了微型逻辑电路。除了通用电路,还有专用逻辑电路,模拟和数字开关电路等——所有这些都是采用尽可能小的封装。微型逻辑电路性能和 Mobile handsets are rapidly evolving. Today’s 2.5G handsets and the 3G and 4G handsets under study will offer higher data rates in the next two to three years, adding more user capabilities and memory. All of these require minimal power dissipation to extend the battery charge interval. In line with this trend, Fairchild has developed micro-logic circuits based on the existing single-gate, dual-gate and three-gate logic functions. In addition to general purpose circuits, there are also specialized logic circuits, analog and digital switching circuits, etc. - all in the smallest possible package.
