Working Principles

The SN74AHCT74RGYR is a dual D-type positive-edge-triggered flip-flop. It operates based on the rising edge of the clock input signal. The data input (D) is transferred to the output (Q) when the clock signal transitions from low to high. The complementary outputs (Q and Q) provide the inverse logic states of the main output.

The flip-flop also features asynchronous clear (CLR) and preset (PRE) inputs. When the CLR input is activated, both outputs are forced to a low logic state. Conversely, activating the PRE input sets both outputs to a high logic state. These inputs allow for easy initialization of the flip-flop.
