Disadvantages: - Limited output drive capability may restrict use in certain applications - Requires a stable power supply within the specified voltage range

Working Principles

The MC74VHCT574ADT operates as an octal D-type flip-flop, storing and transferring data based on the clock input. When the clock signal transitions from low to high (positive edge), the data inputs are latched and stored in the flip-flop. The stored data is then available at the corresponding output pins. The master reset input can be used to clear all flip-flops simultaneously, while the output enable input allows for multiplexing multiple devices.
