Working Principles

The 74AHC74BQ,115 is a dual D-type flip-flop that stores and manipulates binary data. It operates on positive-edge-triggered clock signals. The inputs (D1, D2) are latched into the flip-flops when the clock signal transitions from low to high. The outputs (Q1, Q2) reflect the state of the inputs at the last clock transition.

The asynchronous reset input (CLR) resets the flip-flops to a known state, while the asynchronous preset input (PR) sets them to a specific state. The flip-flops can also be cleared or preset by applying appropriate logic levels to these inputs.
