Working Principles

The SN74AC74DRG4 is a dual D-type flip-flop that operates on positive-edge-triggered clock signals. It can store and transfer binary data using its data (D) input. The flip-flop has asynchronous active LOW clear (CLR) and preset (PR) inputs, which allow for resetting or setting the flip-flop outputs independently of the clock input.

When the clock input transitions from LOW to HIGH, the data at the D input is transferred to the Q and Q̅ outputs. The complementary outputs provide the inverted and non-inverted versions of the stored data. The CLR and PR inputs override the clock input and force the outputs to a known state when activated.
