集成计数器74LSl61的逻辑功能扩展
Logical Function Extension for Integrated Counter 74LSl61
摘要
Abstract
The MSI-based programmable counter 74LS161 is a syne binary accumulator, and is conventionally used as an accumulator with different digital systems. The logical function extension for MIS-based counter 74LSl61 is discussed to develop its unconventional use, in which the logical modification technology is adopted to change its application direction, that is to say, the state output of 74LS161 is logically modified to change its counting regulation so that the state output is back fed to the input end of the setting data to reach the time sequence of "next state=setting data" , and thus the logical function extension is realized. The creative part is that the logical modification technology is proposed to change the application direction of MSI-based programmable counter.关键词
