Working Principles

The SN74ALVCH374DBR operates based on the principles of D-type flip-flops. It stores and transfers data based on clock signals. When the clock input (CLK) transitions from low to high, the data inputs (D0-D7) are latched and stored in the flip-flops. The stored data is then available at the corresponding Q outputs (Q0-Q7). The output enable input (OE) controls whether the outputs are active or in a high-impedance state.
