Working Principles

The MM74HC374WM is an octal D-type flip-flop that stores and transfers data in digital systems. It operates based on the clock input (CP) and clock enable input (CE). When CE is high, the flip-flop is enabled, and data at the D inputs is transferred to the Q outputs on the rising edge of the clock signal. The output enable input (OE) controls the state of the outputs, allowing them to be either active or in a high-impedance state. The master reset input (MR) overrides all other inputs and clears the flip-flop.
