Working Principles

The 74LVC74ABQ,115 is a dual D-type flip-flop that stores and manipulates digital information. It operates based on the principles of sequential logic, where the state of the flip-flops changes according to the clock signal and input data.

Each flip-flop has a data input (D), clock input (CLK), set input (PR), and reset input (CLR). The clock input determines when the flip-flop samples the data input and updates its output. The set and reset inputs allow for forced states of the flip-flop outputs.

The IC uses CMOS technology, allowing it to operate at low voltages while maintaining high noise immunity and low power consumption.
