Additional Details

The TC74HC4040AP is a 12-stage binary ripple counter where all counter stages are master-slave flip-flops. The state of the counter advances one count on the negative transition of each clock input pulse. A HIGH signal on the reset input forces all counter outputs to a LOW state. Due to its ripple-carry design, the propagation delay increases with each stage. The device is provided in a DIP16 package. The available outputs include Q0, Q1, Q2, Q3, Q4, Q5, Q6, Q7, Q8, Q9, Q10, and Q11 representing each counter stage.
