Functional Features

  • Octal D-Type Flip-Flop: The SN74AC564DW consists of eight individual D-type flip-flops, each capable of storing a single bit of data.
  • 3-State Outputs: The outputs of the flip-flops can be put into a high-impedance state using the OE (Output Enable) input, allowing multiple devices to share a common bus.

Advantages and Disadvantages

Advantages: - High-speed operation - Low-power consumption - Compact SOIC package - 3-state outputs for bus sharing

Disadvantages: - Limited voltage range (2V to 6V) - Temperature limitations (-40°C to +85°C)

Working Principles

The SN74AC564DW operates based on the principles of digital logic. The clock pulse input (CP) controls the timing of data storage in the flip-flops. When the CP signal transitions from low to high, the data present at the D inputs is transferred to the corresponding Q outputs. The master reset input (MR) allows all flip-flops to be asynchronously reset to a known state. The output enable input (OE) enables or disables the outputs, allowing for bus sharing.

Detailed Application Field Plans

The SN74AC564DW is commonly used in various applications that require sequential data storage and retrieval. Some typical application fields include:

  1. Microprocessors: Used for register storage and synchronization in microprocessor systems.
  2. Data Communication Systems: Employed in data transmission and reception circuits for buffering and synchronization purposes.
  3. Memory Modules: Integrated into memory modules to store address and control signals.
  4. Industrial Control Systems: Utilized in control circuits for sequential operations and timing control.

Detailed and Complete Alternative Models

  1. SN74AC574: Similar to SN74AC564DW but with latch functionality instead of flip-flops.
  2. SN74HC564: High-speed CMOS version with similar functionality.
  3. CD4013B: Dual D-type flip-flop with similar characteristics.
