Working Principles

The DM74LS393N is a dual 4-bit binary counter that operates based on clock signals. The counter increments its value by one on each rising edge of the clock input. The outputs represent the binary count from 0 to 15 (in binary) or 0 to 9 (in decimal). The counter can be reset asynchronously using the reset inputs.
