Working Principles

The NLV74HC74ADTR2G operates based on the principles of flip-flops. It consists of two D-type flip-flops that store binary data. The clock inputs (CP1 and CP2) control the timing of data storage and retrieval. When a clock pulse is applied, the data at the corresponding D input (D1 or D2) is transferred to the respective output (Q1 or Q2). The complementary outputs (Q̅1 and Q̅2) provide inverted versions of the main outputs.

The clear (CLR) and preset (PRE) inputs allow for initialization of the flip-flops. When the clear input is activated, both outputs are forced
