  • Positive-edge triggered clock input
  • Outputs can be disabled using the output enable (OE) pin
  • Data inputs are latched on the rising edge of the clock pulse

Advantages and Disadvantages

Advantages: - Low-voltage operation allows for compatibility with various systems - High-speed operation enables efficient data transfer - 3-state outputs provide flexibility in connecting multiple devices

Disadvantages: - Limited to octal (8-bit) data storage and transfer - Requires an external clock signal for proper functioning

Working Principles

The MC74LVX574MELG is a positive-edge triggered octal D-type flip-flop. It stores and transfers binary data using eight individual flip-flops. The data inputs (D0-D7) are latched on the rising edge of the clock pulse (CP). The outputs (Q0-Q7) can be enabled or disabled using the output enable (OE) pin. When OE is high, the outputs are active; when OE is low, the outputs are in a high-impedance state.
