N-system counter design based on 74LS16X

A counter is a simple and practical sequential logic device used for timing, frequency division, clock pulse input counting, and clock pulse generation. Based on the above applications, this paper aims at the different characteristics of integrated chips 74LS16X—74LS160, 74LS161, 74LS162, and 74LS163. Specific design methods were adopted, such as the common asynchronous resetting or presetting method, synchronous resetting method, or presetting method. At the same time, according to the resetting and presetting mode of the integrated counter 74LS16X, different chips were selected for analysis and research, and the design method for N-system was effectively obtained.
