Additional Details:

The TC74VHCT574AFT is controlled by a clock (CLK) input and an output enable (OE) input. When OE is low, the outputs are enabled; when OE is high, the outputs are in a high-impedance state. The data present at the D inputs is transferred to the Q outputs on the rising edge of the clock signal. Detailed specifications regarding propagation delays, input and output voltage levels, and power consumption can be found in the Toshiba datasheet for this part. The datasheet also includes timing diagrams and application notes for proper device operation.
