Functional Features

• The 74ACT273MTCX is an octal D-type flip-flop register.
• It can store and transfer data using its eight flip-flops.
• The CLR pin allows for clearing the register to a known state.
• The CLK pin controls the timing of data storage and transfer operations.

Advantages and Disadvantages

Advantages: - High-speed operation enables efficient data processing. - Low-power consumption makes it suitable for battery-powered devices. - Compact TSSOP-20 package saves board space. - Wide operating voltage range provides flexibility in various applications.

Disadvantages: - Limited number of flip-flops may not be sufficient for complex systems. - Propagation delay may affect real-time applications with strict timing requirements.

Working Principles

The 74ACT273MTCX operates based on positive-edge triggered D-type flip-flops. When a rising edge is detected on the CLK input, the data present at the D0-D7 inputs is transferred to the corresponding Q0-Q7 outputs. The stored data remains unchanged until the next clock transition occurs. The CLR input can be used to clear all flip-flops simultaneously, setting them to a known state.

Detailed Application Field Plans

The 74ACT273MTCX is commonly used in various digital systems where sequential data storage and transfer are required. Some application fields include: 1. Microcontrollers and microprocessors 2. Data communication systems 3. Memory modules 4. Industrial automation 5. Consumer electronics

Detailed and Complete Alternative Models
