Working Principles

The 74LVQ374SJX is a positive-edge-triggered flip-flop that stores data on the rising edge of the clock signal. When the master reset (MR) input is low, the flip-flop is cleared, and all outputs are forced to a low state. Data inputs (D0-D7) are latched into the flip-flop on the rising edge of the clock signal (CLK). The output enable (OE) input controls the 3-state outputs, allowing them to be either active or in a high-impedance state.
