The 74HC574 is a high-speed CMOS octal D-type flip-flop IC with tri-state outputs. It is widely used in digital circuits for temporary data storage, data transfer, and interface applications. The IC consists of eight edge-triggered D-type flip-flops, each with individual data (D) inputs and tri-state outputs. The IC is available in a SOIC-20 SMD package, making it suitable for compact and high-density PCB designs.
Features
- Octal D-Type Flip-Flops: Contains eight individual flip-flops, each capable of storing a single bit of data, making it useful for data storage and transfer in digital systems.
- Tri-State Outputs: Features tri-state output control, allowing the outputs to be set to a high-impedance state for bus-oriented applications.
- High-Speed Operation: Capable of high-speed operation, making it suitable for use in fast digital circuits.
- Edge-Triggered Operation: Data is transferred to the output on the rising edge of the clock pulse, ensuring precise timing and control in synchronous systems.
- Direct Clear Function: Includes a direct clear input to reset all flip-flops, providing a quick way to reset the stored data.
- SOIC-20 SMD Package: Compact surface-mount package for easy integration into space-constrained PCB designs.
