Working Principles

The 74LVCH16374APVG operates by receiving input signals on its D1-D16 pins. These signals are then stored in the 16 individual flip-flops. The OE (Output Enable) pin controls the output state, allowing or blocking the data transfer from the flip-flops to the Q1-Q16 pins. The CP1-CP16 pins are used for clocking the data into the flip-flops.
