Working Principles

The MC74VHCT374ADTR2 is a D-type flip-flop with 3-state outputs. It stores and transfers data based on clock pulses. The data inputs (D0-D7) are latched into the flip-flop on the rising edge of the clock pulse (CP). The stored data can be accessed through the output pins (Q0-Q7). The output enable (OE) pin controls the 3-state outputs, allowing them to be either active or high impedance.
