- Simultaneous-Switching Performance of TI Logic Devices (Rev. B)PDF, 378 Kb, 修订版: B, 档案已发布: Feb 23, 2005
Simultaneous-switching noise can generate and propagate glitches in electronic systems. Therefore, system designers are faced with challenges to minimize simultaneous-switching noise, while increasing switching speed and improving signal quality. This report presents the performance of different TI logic devices under various simultaneous-switching conditions. Factors such as the number of bits sw
