Working Principles

The CD74HCT73M is a dual JK flip-flop that stores and manipulates binary information. Each flip-flop has two inputs: J (data input) and K (complement of data input). The state of the flip-flop is determined by the inputs and the clock signal. When the clock signal transitions from low to high, the flip-flop captures the input values and updates its outputs accordingly. The clear and preset inputs allow for additional control over the flip-flop's behavior.
