Design method for cascading applications of integrated counters
REN Junyuan
Abstract：Using the method of decomposition and cascade,an in-depth study is conducted on the design of module-60 counter by using integrated module-10 counter 74LS160.The objective is to explore the conditions under which the low chip counter can effectively trigger the high chip counter within the length of a counting mode and the control conditions for each chip to reset when the counter is cascaded.The conclusion is that there are four cascade design methods:parallel cascade synchronous control reset,parallel cascade asynchronous control reset,serial cascade synchronous control reset and serial cascade asynchronous control reset.The circuit is constructed in Multisim simulation system and verified by simulation experiments.The innovation of the method lies in the presentation of the basic principle of cascaded expansion using intergrated counters,which has improved the design approach for cascaded expansion.
