Working Principles

M74HC374B1R operates based on the principles of digital logic. It consists of eight D-type flip-flops that store binary data. The input data is latched onto the flip-flops when a clock signal is applied. The stored data can be read from the outputs or modified by applying appropriate control signals. The output enable pin allows for enabling or disabling the outputs as needed. The asynchronous master reset pin resets all flip-flops to a known state.
