Functional Features

• The 74ACT534SJX is an octal D-type flip-flop with 3-state outputs.
• It operates at high-speed, making it suitable for time-critical applications.
• The IC has a master reset input (MR) to clear all flip-flops simultaneously.
• It features an output enable input (OE) to control the 3-state outputs.
• The device utilizes advanced CMOS technology, providing low power consumption.

Advantages and Disadvantages

Advantages: - High-speed operation allows for efficient data processing. - 3-state outputs provide flexibility in connecting multiple devices. - Low power consumption contributes to energy efficiency. - Compact SOIC package enables space-saving integration.

Disadvantages: - Limited voltage supply range (2.0V to 6.0V). - Propagation delay may affect real-time applications with strict timing requirements.

Working Principles

The 74ACT534SJX operates based on the principles of sequential logic. It consists of eight individual D-type flip-flops that store binary information. The clock input (CP) triggers the transfer of data from the input pins (D0-D7) to the corresponding output pins (Q0-Q7). The master reset input (MR) clears all flip-flops when activated. The output enable input (OE) controls the 3-state outputs, allowing them to be either active or in a high-impedance state.

Detailed Application Field Plans

The 74ACT534SJX is commonly used in various digital systems and applications, including:

1. Microprocessor-based systems
2. Data storage and retrieval systems
3. Communication equipment
4. Industrial control systems
5. Automotive electronics
6. Test and measurement instruments
