Working Principles

The 74ABT374CMSAX operates based on the principles of sequential logic. It consists of eight individual flip-flops that can store and transfer data. The clock signal controls the timing of data storage and transfer operations. When the clock enable input is active, the flip-flops respond to the clock signal and update their outputs based on the input data. This enables the IC to hold and propagate data in a controlled manner.
