• Positive-edge triggered clock pulse (CP) for synchronous operation
• Data inputs (D0-D7) for storing and transferring data
• Outputs (Q0-Q7) to provide the stored data

Advantages and Disadvantages

Advantages: - High-speed operation - Low power consumption - Compact package size - Wide operating voltage range

Disadvantages: - Limited number of flip-flops (8 in this case) - Not suitable for applications requiring a large number of flip-flops

Working Principles

The SN74HCT273PWG4 is an 8-bit D-type flip-flop that stores and transfers data. It operates on positive-edge triggered clock pulses, allowing synchronous data transfer. The asynchronous clear function resets all flip-flops to a known state when activated.
