Functional Features

  • The CD74AC273M is an octal D-type flip-flop with clear functionality.
  • It operates at high speed and consumes low power, making it suitable for various applications.
  • The flip-flop outputs are buffered for enhanced performance and can drive standard TTL loads.
  • The clear input allows for synchronous clearing of all flip-flops.

Advantages and Disadvantages

Advantages: - High-speed operation enables efficient data processing. - Low power consumption helps in reducing energy usage. - Buffered outputs provide improved signal integrity. - Synchronous clearing simplifies control logic.

Disadvantages: - Limited number of flip-flops (8 in this case). - Requires an external clock signal for proper operation.

Working Principles

The CD74AC273M is a sequential logic device that stores and transfers data using flip-flops. It operates based on the positive edge of the clock pulse. When the clock pulse transitions from low to high, the data present at the inputs (D0-D7) is transferred to the corresponding flip-flop outputs (Q0-Q7). The clear input (CLR) allows for synchronous clearing of all flip-flops when activated.

Detailed Application Field Plans

The CD74AC273M can be used in various applications, including:

  1. Digital counters
  2. Shift registers
  3. Data storage systems
  4. Address decoding circuits
  5. Control units in microprocessors
