The 74HC393 handles this entirely in hardware. This 14-pin integrated circuit houses two completely independent 4-bit binary ripple counters. Because it contains two distinct counting blocks on a single chip, you can use them separately to track two different events, or easily cascade them together to create a powerful, single 8-bit counter capable of counting from 0 up to 255.\u003c\/p\u003e\n\u003cp data-path-to-node=\"4\"\u003eEach 4-bit counter works by listening to a negative-edge clock input. Every time the clock signal transitions from HIGH to LOW, the counter increments by one, outputting the result across four parallel binary pins. Each stage divides the incoming frequency by two, making this chip incredibly effective for scaling down high-frequency oscillator signals. Additionally, each counter features its own dedicated, active-HIGH Master Reset pin. Pulsing this pin instantly clears the entire 4-bit count back to zero, giving your system total control over specific counting limits and cycling sequences.\u003c\/p\u003e\n\u003cp
