Working Principles

The SN74LVC374AQPWREP operates as an octal D-type flip-flop with 3-state outputs. It is positive-edge-triggered, meaning that the stored data is transferred to the outputs on the rising edge of the clock signal. The common clock and enable inputs control the operation of all flip-flops simultaneously.

When the clock input (CLK) transitions from low to high, the data present at the D-inputs is latched and stored in the flip-flops. The stored data is then available at the Q-outputs. The output enable input (OE) controls whether the outputs are active or in a high-impedance state.
