摘要
以一种典型的中规模集成(MSI)计数器芯片同步十进制加法计数器74LS160/162为例,采用反馈置零法(复位法)和反馈置数法(置位法)来构成任意进制计数器。最后总结出详细的设计步骤。
74LS160/162 is introduced as a typical middle scale integration (MSI) counter chip which is adopted here to design an arbitrary value counter. Feedback purchase zero law (replacement law) and feedback purchase number law (set bit law) are mainly adopted here. Finally the detailed designing steps will be given out.
