Functional Features

The SN74ALS273DWRG4 is a D-type positive-edge-triggered flip-flop. It has the following functional features:

• High-speed operation: The flip-flop operates at a fast propagation delay time of 9ns, making it suitable for high-speed applications.
• Low-power consumption: The IC consumes only 22mW of power, making it energy-efficient.
• Clock enable: The flip-flop has a clock enable input (CP) that allows control over the clocking of data into the flip-flop.
• Clear function: The clear input (CLR) resets all flip-flops to their initial state.

Advantages and Disadvantages

Advantages: - High-speed operation enables efficient data processing. - Low-power consumption reduces energy usage. - Clock enable feature provides flexibility in controlling data input. - Clear function allows for easy reset of flip-flops.

Disadvantages: - Limited number of flip-flops (8 in total). - Restricted voltage range (2V to 6V).

Working Principles

The SN74ALS273DWRG4 operates based on positive-edge triggering. When a rising edge is detected on the clock pulse (CP) input, the data present at the D0-D7 inputs is transferred to the corresponding Q0-Q7 outputs. The clear input (CLR) can be used to reset all flip-flops to their initial state.
