Working Principles

The MC74LVX574M works by storing and transferring data using its eight flip-flops. When a clock pulse is received at the clock input (CP), the data present at the D0-D7 inputs is latched into the corresponding flip-flops. The stored data can then be accessed from the Q0-Q7 outputs. The output enable (OE) pin controls whether the outputs are active or in a high-impedance state.
