Working Principles

The 74F112SJX is a dual J-K flip-flop that stores and outputs digital data based on the inputs provided. Each flip-flop has two inputs (J and K), a clock input (CLK), and set and reset inputs (S and R). The J-K flip-flop operates based on the clock signal, where the input data is captured and stored at the rising edge or falling edge of the clock pulse.

The J and K inputs determine the output state of the flip-flop. When both J and K are low (0), the flip-flop remains in its current state. When J is high (1) and K is low (0), the flip-flop toggles its state. When J is low (0) and K is high (1), the flip-flop resets to a specific state. When both J and K are high (1), the flip-flop is in an undefined state.

The set (S) and reset (R) inputs allow for forced state changes in the flip-flop, overriding the J-K inputs. Setting S to high (1) forces the flip-flop to output a high state, while setting R to high (1) forces the flip-flop to output a low state.
